I don't particularly see any need to to have live streaming from the Wii U when you can just use the web browser and go watch it on any of their live stream channels. Why not take advantage of already established services like YouTube and UStream, which are probably going to be better than Nintendo could do themselves. If you don't want to watch it live, you then also have the eShop version that's up pretty quickly after any of the Nintendo Directs and watch it there in pretty decent quality from my own experience so far.

About the social features, you obviously think Nintendo's offering with Miiverse is somehow detrimental and can't compete with PS4's. Like SCAR392 said, whatever floats your boat. I personally am happy browsing the Miiverse channels knowing I don't have to get in some nonsense debate with morons and I think it's simplicity is what makes it great. This is something Sony and MS never quite get, they start adding every possible feature you could ever want, but what happens is it's just a mess and creates more issues than it solves. I learnt my lesson well from Xbox360, paying a yearly fee and virtually never playing online games. I tried the chat a couple of times and had to mute about 20 people, whiny little teens, teens who shouldn't even have the games in the first place because they were 18 rated, yet a 13 year old mouthing off wasn't a fn experience.

I'm not convinced Sony's uploading videos features is anything worth writing home about but maybe I'll be proven wrong when it is in the hands of gamers. I do think the being able to jump in and help people is a good use of it, but to be honest even with that, I'd rather just play games myself. It's like were getting to the stage that it's not even YOU playing the game but watching OTHERS play it, is that what people really want in a games console? I'd rather just watch TV.

@SCAR392
As for features, I'd like to see folders just for organising demo's and apps on my home screen. I think it's a much more intuitive use of the touchscreen rather than having to scroll through 8 screens or whatever it is at the moment.

I'd like to see DVD & Blu Ray playback if it's possible, but something that would be a service you unlock, so you pay maybe to unlock it and that covers any licensing issues. It would appease anyone with DVD's/Blu Ray's and help bridge the divide between features of the other consoles, therefore increasing the console perceived value.

I'd like to be able to OFFICIALLY stream music/films from my PC/iMac or at least have a service/feature that allows it from a hard drive even. If Nintendo could get a service on there like iTunes (unlikely) or Pandora say, then that would be great. Again this could be a paid feature, just as long as it's offered and allows the ability to do what other consoles can do.

Other than that, it's just user interface improvements like the speed of it & some cleaning up of how you access services. For instance when your on the web browser and you want to quickly check Miiverse because your light flashed, you press the home button but if you decide you just want to go back to the browser, you need to load it again, I'd rather it suspends it like it does when you are playing a game and go to the browser, so that when you return to the game it doesn't need to load up again.

Actually I'd also love Nintendo to release the tech demos for Zelda and the Japanese Garden that they had at E3 2011. It would be cool as a little bonus and nice to see what's potentially coming in future games. It's all good looking at Youtube videos but I'm sure it would be fun for Wii U owners to try it out for themselves and see what everyone was so excited about.

EDIT:
I also forgot about wanting a General Miiverse channel asap. I know they said there will be the ability to create channels or something but it's the most frustrating thing about the service at the moment. You want to just chat but you have to go into a specific games channel and it's just a bit awkward in that sense.

@CDdreams

Well having an interface made for the TV than just looking at a web browser page is better imo. Not only that but you get a degree of connectivity you don't get just from using Ustream . For example you could have the stream integrated to miiverse. When Microsoft live streamed the spike VGAs they used a voting system where the watchers could choose what and the DJ would play next and what game reveal would be shown next as well.

As a company the stream gets increased visibility compared to using something like ustream in a browser .As people who are plugged in we know to go for a a nintendo direct when they are only announced hours in advance. But take Microsoft's E3 press conferencefor example they live streamed t off of Xbox live and in the days coming they advertised a E3 i =n the square where Halo 4 is in the picture below.

so when it came time to watch I saw a few of my irl friends who probably wouldnt watch E3 other wise tune in to the app.

@Sony_70
Don't get me wrong, it would be great if they streamed directly on the Wii U itself. In fact if they had some kind of Miiverse integration like TVii does for shows, then it would be incredible, maybe it's part of their long term plan. However I think right now it would be an expensive endeavor, I assume, to get servers and streaming technology to do so and I think Nintendo really needs to focus on resolving more fundamental issues first.

So although it would be nice, it's adequate with the current setup with room to improve.

Sometimes the bits of chocolate in my Mint Chocolate Chip get stuck in my teeth, though. Or Cookie Dough!

The one thing that immediately comes to mind is folders. I like how my 3DS menu is organized and would really like to bring that organization to my Wii U. I've only downloaded a few things, but already my menu feels like cluttered chaos.

There's nothing stopping them technically, it's just a matter of whether they want to. Of course there's nothing to stop a user from getting a hardware RAID drive, but it means spending more for an integrated unit or doing it yourself. The last inexpensive RAID enclosure I bought had a fan that was way louder than what I'd want in my lounge.

I'd settle for the ability to copy data between drives (mirroring is basically just automated copying between drives), but it could be that Nintendo is extra paranoid about people being able to copy stuff like game save data since that was a vector for hacking the Wii. Mirroring doesn't have to include access to data outwith the channel level though, so I hope they let us do it.

Screenshot feature for 3DS please.

On the topic of Wii Speak or the Vitality Sensor... No, Nintendo doesn't revive dead technology. Remember the e-Reader for the GBA? Like 3 games used it and then it got forgotten. Aside from the novelty, it was unpractical, even a small minigame could require up to ten cards to read. Wii Speak is just as unpractical in the face of good headsets. And the vitality sensor... Yes, I could think of a couple decent ideas for it but in the end it was so gimmicky that even Nintendo realized it was a waste of time.

Anyways, my big change I want is achievements. The competitors all have them, and a firmware update could add them. Come on, Nintendo!

If they used it for voice commands like Xbox 360's Kinect, it could be used again. Really, there's tons of uses for Wii Speak. The technology isn't dead, just the Wii Speak name. The Vitality sensor technology isn't dead either. They use that sort of thing is health clinics all the time. Again, the name and use of these peripherals is the only thing dead here. The Mic on the Gamepad only used for the DK minigame and Wii U chat as far as I know, and I don't know about you guys, but I kinda want the Vitality sensor thing, too.
That's like one of the main procedures at the docter in your check-up.

There are ways to get media on your Wii U, it just has to be set up manually instead of just commanding the Wii U to do it. We all know Wii U can play CDs and DVDs. Possibly even blurays, but Nintendo doesn't have the licenses to let users do that. Nintendo could charge for it, but then what the heck are most people going to do with their other gadgets? I think they are working more on media software. That last announcement about encouraging HTML5, Java, and other media related coding is sign of improvment. I think by the end of this generation of game consoles, people will be able to get the best quality of music, video, and games online, without having a dedicated service like Netflix.

Nintendo wants to keep things simple, just keep that in mind.

I know what they do at my doctor's check-up, I'm not an idiot. But I'm not going to the doctor because it's fun, I'm going for my health. Yes, there is ways it can be applied for games but for one almost no one wants to play a game with that thing on their finger, it's cumbersome and unpractical. In truth, if Nintendo release it they'd use it for three mediocre and gimmicky games, tops. Then it'd get forgotten. Heck, the only reason the balance board isn't dead is Wii Fit centers around it and is a widely popular franchise already. I have a Wii Speak peripheral and I see no reason for it to be used again. Headsets are more practical. Nintendo will not bring any of these back. It's just a waste of their development costs, a vast majority of gamers prefer a headset and have little interest in the vitality sensor. It's one of those things I'd excitedly buy for one overhyped gimmicky title and lose interest with in two weeks, burying it in my closest to never see again. I'm glad they let that idea die before it came out, saves me money on yet another accessory that I'll hardly touch and developers wouldn't bother incorporating. Nintendo has sold me enough of that junk over the years. (Not bashing Nintendo either, I love their innovation but just in truth they've sold me on too many accessories that they barely utilized).

Well, if they made the vitality sensor a pack-in with Wii Fit U, everyone that had that game would have one. You're supposed to check your pulse before and after exercise to test your heart rate. If people are expecting voice commands like on Xbox 360, they'll bring some form of Wii Speak back.
I understand these things can seem like gimmicks or useless altogether, but they do have uses.

Most people don't check their pulse before and after a workout, and those players would ignore it even if it was a pack-in. In fact, I hardly know anyone who bothers with the wrist straps on their Wii remotes, Nintendo only includes those to cover their butts legally. Packaging vitality sensors with the next Wii Fit would just be a waste of Nintendo's money.

As for the Wii Speak for voice commands, it's still obsolete when we have a mic right in the gamepad.

The chances are Nintendo will use a variant of the Vitality Sensor in a future product. Maybe the next handheld or home console controller.

If you look back at Nintendo's history over the years, they test things out and sometimes you never hear about them for years, then all of a sudden they will bring something out that used the same tech, albeit updated, but they incorporate it into something current. The 3DS is the perfect example.

They had Game & Watch, then evolved to Gameboy, a single screen device, eventually many years later going back to the design and idea for the NDS & 3DS. Even the 3D part is an evolution of the Virtual Boy, just modernised with colour graphics and without glasses.

I wouldn't be surprised if the next handheld has some sensor built into the back of the device where your hands grip, or maybe on the next home console in 5 years time. Think of the Gamepad with it's little ergonomic handles at the back and imagine a sensor on them. That's how they will evolve the controller next gen, vitality sensor, higher res screen, and other unknown features. I'm sure if you look back at failed or tested ideas from Nintendo's past, you could work out the next controller to a certain degree.

As for the Wii Speak for voice commands, it's still obsolete when we have a mic right in the gamepad.

Exactly, they repurposed the Wii Speak already and it's the mic on the Gamepad. It's the perfect evolution of Wii Speak if you think about it. Instead of having a microphone that is impersonal and picks up everyones voices around you and limiting it's functionality to that room it's placed in, it's now on the gamepad giving it mobility and making it much more personal. It's probably much more accurate as a result. Anyone who has Wii Speak does't need it now except for backwards compatibility possibly.

The good thing is, in the Gamepad it's not going to become obsolete over the Wii U's lifespan because it's integral to the console now.

There's even more techs that never actually see the light of day. It's more likely the vitality sensor will fade into obscurity until it's discovered as a treasure in Pikmin 6 or something like that (if it's lucky).

I would be interested in the Vitality Sensor coming back in a few years. When developers have gotten more use to building engines that can randomize environments. Could you imagine a horror game that ramps up when ever you heart rate goes back to normal, waiting until the moment you relax and then it throws the worst enemy at you. It will just take awhile for developers to catch up to the Vitality Sensor

Yes but could you imagine playing the game with that thing on your finger? It could totally break immersion, hardly looked comfortable while holding a controller. The only way I could see it practical would be if the controller itself could sense your heart rate without wrapping around a finger, and I don't know if that even is possible or if it would be a realistic price. And would the player buy the controller just for that game or would the feature be added to the console's controller just for one or two games? It still seems unrealistic to me even if there are a couple uses it could have. I think Nintendo was right to let the idea go.

@ShadJV

If you go to the gym and you look at running machines/treadmills or cycling machines and how they have the sensor on the bars themselves, well that's how they'd integrate it. On the controller, there would be a small metallic strip, ergonomically integrated so that when you held the controller naturally, your finger/s would cover the strip and you'd get a reading. It would be cosmetically unobtrusive and seamless to the user.

I realize that but how much does that technology cost?

@ShadJV

Yep it will be awhile until we see it built in
