well, it's just from what you have described, it's still the same firmware analogy that I typed up in another thread, it's a specialized I/O device with some advanced camera tech, I'm still not seeing anything that's truly different. so I was asking if you had any hard document on it so I can check but meh.... guess we have to remain in speculation until next year.

Check out some of their tech demos and papers. Microsoft used GestureTek technology in Natal. Sony actually uses part of their API in the EyeToy but it is very limited and can't do the things which Natal can do. It's 2D vs 3D.
