Well, if they can show me a good reason on why I should want the camera I wouldnt mind paying a little extra for it. However, neither company has really shown me a reason to want it.
I remember being pretty excited about kinect because of the possibilities of new gameplay, but it ended up just being a broken motion control mini game playing device. The new kinect doesnt really look much better.
Playstation eye/move also has potential, but sony has refused to really put any meaningful effort behind it.
