I've been playing with a guy at work's Kinect and although I hate the Wii style games that saturate it at the moment, it does look like it could own all for real games in the future. Crouching/prone by actually doing it, aiming with a real gun, melee by actually pulling a knife. Imagine RPG combat outcome determined by your actual physical ability raher than levelling. I'd love that.
A slight majority of a statistically worthless sample size agree.
