We just left a behind-closed-doors demo of the upcoming "Project Natal," codename for the Xbox 360 camera/motion detector/voice recognizer/Minority Report-is-reality device Microsoft introduced at its E3 press conference this year.

Guess who's in the next group following in after us to see Natal? Mario creator Shigeru Miyamoto himself, along with NOA Senior Manager of Product Marketing (and frequent on-stage demo guy) Bill Trinen and the rest of his Nintendo entourage.

We couldn't see Miyamoto's reactions to Natal, or if he got a chance to play any of the demos (the human Breakout seen at the press conference and a Burnout Paradise tech demonstration -- more on these later) himself, but just his apperance in this private area of Microsoft's booth got everyone there buzzing.

Wonder if he broke out in a sweat from jumping around in front of the camera -- or from seeing what it's capable of.
