Definitely more than eye toy or even the original Xbox 360 "vision" camera. I don't know all the details, but I think there are at least two cameras in there, plus motors of some sort (sorry, I really don't have any inside info) so it should go far beyond
what is possible with a regular camera based system. Compared to the Wii, it is also completely different as it is tracking *you*, not the controller. Considering what a controller or a camera or similar devices cost I think the price is reasonable. Of course,
I'm still trying to justify a completely new Xbox 360 (the new shiny black quiet model) when the one I have is working 100% at the moment ... not quite there yet, but I'm sure I'll figure out a good rationalization.
The thing is, I actually think the price is pretty reasonable for a 3D motion tracking camera, because that's still kind of amazing futuristic technology, and the fact that you can get that for less than $200 is amazing.
As a peripheral for video games, though? Insanely expensive. I can't even justify getting the $300 bundle when my current 360 breaks down because that version doesn't have a hard drive. So if I want Kinect and a 360 with a hard drive, I'm going to have to
spend, what, €450? And that's without any games. If I want at least one Kinect game, I'm out over $500. What crazy marketing research did they do to consider that a good deal?
