Microsoft Faithless In Kinect?

Microsoft have revealed that Kinect will NOT be able to read sign language as was revealed by its patent. Microsoft have put it nicely by saying not everything they put to patent is brought to market immediately, however sources close to Kinect have apparently popped up saying the ability to read sign language had to be removed when the resolution of the camera was halved during part of a dumbing down process... and here's the kicker, the source goes on to mention the camera was dumbed down to make it cheaper in case Kinect failed to sell well. Seems like even Microsoft are a little doubtful of Kinect's success. Not something you want coming out with Kinect's launch in less than 3 months.
