Cabe, this is a very interesting development, not the least in that it involves movement and perception in 3D. Looking at the video you can see the game influence. My son likes to play minecraft. There is even someone who made electrical elements, so you could make a circuit, even a computer with the game. Of course, the types of things that are in the video seem to be sort of conceptual. I am not sure if this is a real game changer. Using a keyboard and mouse people have made some pretty amazing and complex things with minecraft, for example.
When I think of CAD I think of precision. I am not sure this interface gives you that.
Another interesting thing is the use of hand held controllers. I wonder if they looked a gestures only. That would be really interesting.
