I saw this on TV earlier today and think it is one of the best features they have ever had on the show, and hopefully show the future of what games can be for everyone.
It involved them playing battlefield, on an omni-directional treadmill, on a 360 degree domed screen, with paintballs gettin shot at you when you were hit in the game, using your body to run around the map, jump or crouch
The videos just show how good it is
This is the teaser trailer released last week but you get the idea of what they did
Here is the full feature (I think? didnt watch it all)
Abolutely AMAZING definately what microsoft had in mind when they made kinect
