I'm still waiting for the second release of an improved kinect. This version have some serious limitations like very low resolution, and extremely low frame rate. I think this is because the limitations of USB 2.0 port, but this cam be done using USB 3.0 without any problems...I think.
So we needs for PC HD cameras and at least an 60Hz output to match all the monitors/tv out there. Then I would be really interested.
