This is video taking apart the Xbox Natal demonstration and trailer and comparing it to Playstation Eye Toy (PS2) and PS Eye (PS3). Each has promised the same things at some point and each probably managed to pull it off, except only under the most precise conditions.
I know Eye of Judgement was impressive when they first showed it; but when the game actually came out, it only ran under just the right lighting conditions. The Eye Toy games ran even worse.
Project Natal most likely will top the PS Eye but not enough. There is no way its going to work in low light rooms. Motion games will still be a gimmick this generation, we don’t have the technology to make work it effectively at a price people will buy it.
