Mario of course. But if not that i want a new ip. Cmon nintendy..
Mario would be awesome, it would be a real surprise if the Wii U launched with a new mario. But I'm thinking there are other Nintendo franchises which have been left out of the spotlight for far too much time, some that may have even been abandoned (Star Fox, F-Zero, etc.)
I know it would be difficult for Nintendo to release many 1st party Nintendo games at launch so I'm betting for a really REALLY good launch window of games like Mario, Starfox, Metroid, Pikmin etc. Make it happen Ninty.
nintendo forever . . .
