To everyone above, go watch the Dr. Marks videos. They're quite insightful as to what was going on with the tech. For 3D tracking, there was kinect, and there was a brightly coloured object. To tell the truth you can do a lot of what Move can do with just a ball and a stick (Which was demonstrated). So when they were weighing in options; expensive camera for 3D tracking, or a ball and a stick... for 3D tracking. Both did the same thing at the time and one is a lot cheaper than the other.
