The big difference between the PSEye and Kinect is the depth camera. Without it the PSEye can only emulate what the Kinect does. Of course when you throw in the MOVE you get more versatility, but it still can't compare.
Depth sensors are no new thing, but Kinect is the first time the technology has been available for so cheap. Just look what people are doing with it.
The Wiimote and Move are limited in that their input is merely planes in a three dimensional space. Kinect uses its depth sensors to create actual three dimensional shapes. What people are doing with that input is unbelievable.
