Kinect is a revolution, no use of controlers, recognizes your boddy in 3D, voice control, all this is much more appeling than Move, the only problem is the price, if they sell it for U$ 99 the sales would be much higher, can you imagine if it was U$ 49?
Move games are serious, kinect games are fun... that's the hole point, Sony didn't learnd with Wii.
Price is the only problem of kinect.
