A port of FF XIII and XIII-2 plus the announcement that FF XIII-3 is coming to the Wii U. That and Deus Ex are my best bets.

Please, God, let it be a worthy sequel to Crystal Chronicles!

It exceeded expectations by square enix, and is my favorite game this gen. But, it still didn't sell that many, It sold 2.76 million, plus steam sales. So it probably sold more than FFXIII-2 which sold 2.92.

 Tomb Raider will out sell it, FFXIII outsold it, and Hitman Absolution outsold it so it would be a strange pick to port, being's it's also the 2nd longest aside from FFXIII (Meaning most work) and the oldest aside from FFXIII. Being's Tomb Raider is the newest game, and generally well received it would make sense to port that game to me. Also, Deus Ex is easily the worst looking game of the bunch, so it can't sell on graphics like hitman, Final Fantasy, or tomb raider could.

I don't know. Can't wait to see what it is though.

I'll bet that it is Deus Ex or FF13 Collection ports.

:D

That would be awesome. Maybe player one could use the GamePad and players two, three, and four could use a 3DS?

Well it's Square Enix so I'm guessing it's a game that got green lit 3 days ago, and we'll probably get a 30 second CG trailer that makes no sense whatsoever. WiiU owners will be waiting the next 6 years in vain while Square continues to release more sequels to Final Fantasy 13. Of course they could try to mimic their performance at the PS4 reveal and show that tech demo again.

I'm talking about home console, but that's a good start. Now it's turn of the WiiU

Hope it's not Deus Ex: Human Revolution. It might be.
