Why does everyone think Natal will be huge?

[A Bad Clown]

Marketing: Microsoft has done alot to market it, getting in Popular Mechanics and on alot of shows is just the beginning. Microsoft can hype the hell out of stuff, and it works pretty well.

Casual gamers: The biggest market now, they'll look for anything cool like a "wand" or 3D. Natal will make them say "The camera does what you do". They will tell their friends about it, and the cycle will begin.

Price: Instead of buying add ons which make the controller half the price of the system, there's just a camera. The cheap will buy it because just because of the price.

There's alot of reasons Natal could work.
