Personally, I'd like to see a Super Mario 64 caliber 3D Mario game as a launch title. A high-def revisit to the Mushroom Kingdom. I think that it would sell well, be a technical showpiece for the system, and hell- It's a Mario game at launch! When was the last time we saw a Mario game at launch?
Yes that would be great but they need more of a hardcore 1st party launch game. As of right now I'm looking to get assassin creed 3 which looks awesome and believe it or not killer freaks from outer space. Something about the game I like.... This is hoping that graphics are hughly improved over E3 showing.
