I'm thinking it might be the Pokemon fighting game GameFreak teased.

It "includes" a new game according to this page/tweet.
So we may see another game that was already announced.

Zelda Wii U. With a surprise appearance from Aonuma or maybe even Miyamoto! Aonuma even said that he wasn't ready to showcase it yet but as soon as he finished with ALBW's promotion at Comic Con he would start work on an announcement for Zelda Wii U. And he even wanted to show something at Comic Con about it, but didn't, due to focusing on ALBW. Another thing, a lot of people are taking his previous comment,"I'll say more at E3 2014" as "I won't say anything at all about Zelda Wii U until E3 2014." Stating that you will say more at a future event, doesn't mean that you won't say anything sooner than that.

Miyamoto's new IP?

Reggie bits- chances of Smash Bros. inclusion, more Year of Luigi stuff next year, VGX, and more

• Reggie said Mr. Sakurai might consider adding him to Super Smash Bros. if 100,000 fans sign the petition
• Pokemon X/Y are about equal in terms of sales, but Reggie thinks X will end up selling more
• Reggie: Wii Remote was an innovation that opened up gaming to multiple generations
• Nintendo will continue with some Year of Luigi stuff in 2014
• Reggie says he would have never imagined the Wii Remote when he joined Nintendo
• Reggie: Don’t know what hardware will look like in the future, but our games will make you smile
• Reggie: We’re aware of fan wishes but have to do what’s best for the company
• VGX appearance won’t be recorded; no hints as to what’s in store
• Reggie has a 3DS in each of his back pockets, one of which is the gold XL

Oh, good guess! I've all but forgotten about that tidbit.

im gunna say zelda

oh no! looks like they're still at 35,000 signs(unless I'm looking at the wrong petition)

Please tell me you're joking.

What's that supposed to mean? It won't be shown on TV?

I'll say a teaser video for something like X, maybe with a tentative release date. I highly doubt they will announce a Zelda game. The goal at a foolish event like this is to appeal to every clown watching. Zelda,nor any known Nintendo IP would deliver. It has to be X.

You mean the one they confirmed was only a tech demo?

It was? Well that's disappointing...

If they show Zelda, they'll steal the show. That much would be certain.

I just hope all this hype ends up being worthwhile. If it turns out to be a simple announcement for Cranky Kong or something I'm gonna be ticked. >:[

so you won't like if it's a bunch of screenshots of Reggie as a playble Smash Bros. Character?

@WingedSnagret Like I said before... the VGX are a dudebro show and I highly doubt the VGX would let Nintendo announce something like freaking Cranky Kong in the show. It would be too random and might ruin the mood of that silly show. I bet the guys behind VGX would say, "Ummmm... no. You can announce that in a Nintendo Direct. You can't do that here."
So thats why I think Nintendo is gonna announce something legit.
Realistically... I expect trailers for Bayonetta 2, Monolith's X and something random like a Legend of Zelda: Wii U screenshot or Shigeru Miyamoto's IP.

It's gonna be exciting waking up on Monday morning to find out what it is that's for sure.

It's at Saturday night, albeit really late where you're at. Unless you're unable to see it until Monday.

I'll agree with those that think it has to be something to appeal to the Spike audience.

Bayonetta 2 or X.

I don't think they'd reveal Zelda U or something like that on Spike TVt. An announcement like that will come straight from Iwata, Aonuma, maybe even Miyamoto, but not Reggie on Dudebro Network.
