And it actually looked pretty cool.  They played the dodgeball block smashing game, which looked the same as we've all seen already.  But they also played Burnout Paradise and Natal was able to see if the gas was being pushed, so it wasn't just moving at a constant speed, acceleration was possible!  I'm not necessarily interested in owning this, but it's definitely pretty cool.

Yeah, it was cool and everyone seemed to be into it.  Kudo could have sounded like less of a salesman.

I still noticed it glitched out a little when jimmy stepped in during the ball demo. He swung at it and missed, and his arms and body kinda flailed around. John Krasinski was laughing in the background, and it looked like it was more about the glitch than jimmy missing the ball

I loved how ridiculously psyched Jimmy Fallon was. He was just bouncing around like a kid in a candy store. Really great to see this on a major talk show.
