This is great. Don't expect Project Natal to be anything like that, though. It will be crap. But what comes after it and what comes after that, on the other hand, will be very interesting.
You know what's even more fantastic? 3D technology is making leaps and bounds. Before long not only will we be playing video games like that, but they will be in 3D.
I really hope that thing takes off. All the little kids who do nothing but play video games are going to turn out trim and fit from all that activity.
