Motion an voice regconization for the Xbox360

the natal project which Microsoft unveiled at the E3 expo..

the Xbox automatically recognize who you are. the menu from xbox360 could be control using your body.when a voice command is given the natal automatically do the stuff u ask. for a clearer view of natal project please do watch the video.
release date: after a few games which is natal enabled are available
price: i guess i wouldnt be too expensive ...they must compete with the Wii...because the price of Wii itself is far more cheaper then the xbox360 and ps3
Features: Multiplayer this things will make the xbox360 as fun as the Wii, but Wii itself had been in the market for quite a long time.im sure nintendo will be releasing a new console with a better concept soon.
