I thought i share what i found but remeber to take it with a grain of salt

Reggie has supposedly confirmed that the Wii U can support 2 tablet touchsreen controllers. This information was found when Wedbush Morgan’s analyst Michael Pachter talked to Reggie Fils-Aime’s upcoming console.

Pachter says…

“They were particularly unclear about whether the console would support more than one of their tablet-like controllers; Mr. Miyamoto said no, but Reggie said yes (to me in a meeting). Obviously, they intend to ship the console with only one of these controllers, so it is unlikely that anyone will develop games that require two, but they were not clear whether the capability exists.”

Until now we were led to believe that the Wii U supported only 1 tablet controller and other players were forced to use their Wii Remotes. Whether developers will actually develop to utilise 2 controllers is a different matter. The individual tablet could also be very expensive considering the technology it utilises so this may cause Nintendo to discourage local multiplayer using tablets.

Two controllers is excellent news. Just the right amout if you ask me, considering how expensive and fragile it is.

Although, I must say that the whole 'Will developers develop games for two controllers?' question is quite plausible. But if we get, say, ranges of two-player mini-games and software like Wii U Sports or so, I don't see why not. Portable continuity of playing with just the two controllers between two players! It's rather ingenius if you ask me.

Although, in this bit of news, I seem to fish out a few holes with uncertainty. I'm taking this with the ever-so-slightest grain of salt.

I think trying to consolidate a bunch of different of different hardware all to work on one system is a bad idea. With 1 tablet, 1 GC conntroller, 1 wiimote, 1 nunchuck, a classic controller, and a balance board all going at the same time, things can get confusing.

well realisticly whos going to make a game working like that? even if or the console is capable i doubt anyone is going to ultilize unless depending on the game and how much power it would take to do said things

That would be hilarious to have a game that uses every controller and attachment configuration possible all at once. I would play it.

There are no GCN controller ports though, by the way, so that's one controller to scratch off the list. CC(P) is just as good anyway.

I don't believe the real question was ever whether or not it could technically handle 2 or more, but whether or not that will be part of Nintendo's strategy.

Clearly, the controller is expensive, and they have hinted that it will not be available for separate purchase. They're trying to sell the concept that the controller is a fundamental part of the system, and therefore building gameplay around using it along with other wii controllers for other players.

It's hard to imagine them making a game that requires 2 of the new controller, if it really is only sold with the console, because that would have the rather steep requirement that your friend(s) already own the system as well. So, it looks like the vast majority — if not all — of the multiplayer will probably center around one new controller mixed with others. I'm okay with that, insofar as I love asymmetrical multiplayer, where you're not all doing the same kind of thing.

I'll take Iwata's word over Reggie's any day. What it seems to me is simply that they don't know anything yet. The Wii U is still just a working prototype; They have yet to decide things like how powerful, how costly, how many controllers...
The bean-counters will get back to us on all those questions at a later date.

Why not just let the 3DS be the controller? It has all the same fuctions plus it has 3D visuals...

lt's already been said that the WiiU can support up to 4 controllers in "standard definition". I think I read it on the WiiU Blog and Engadget.

Still not 4.

Uh huh.

Stop living in the past and forget about GC controllers. That's like saying you want the N64 to support the NES controllers.

I'm pretty certain ieither read somewhere, or possability in the interview on g4TV the week of E3 that it was confirmed Wii U wouldn't be backwards compatible with GameCube games, Plus, a video I saw somewhere didn't confirm any ports, either.

This is the only thing that makes me cautious about the Wii U. Everything about it is awesome, but if it can't support 4 tablets, or at the very least two, then that's not good enough. Well, to be fair, Iwata said it wasn't a technical limitation, it was more of a price issue for the consumer. Oh well, just let us buy more controllers. We'll pay Nintendo, we always do.

If that controller is going to force us to do weird things that could be done with a single button pressed, then better even to get totally rid of it. I really dont want to "watch" to the TV "through" the controller in order to aim a bow, use a shield or look around. That would lead to the most unpleasant way to play games (not counting the barbaric Kinect idea).

we can't stay stuck in the past our whole life dude

You know, I'd like bringing my wiiu over to my friend and play, say, monster hunter wii U together just through me bringing the controller. We could even hop online with our own characters and have a local online blast.

A second wii u screen on one mothership makes sense in certain ways.
