If Kinect is a huge success . . .
will wii and sony try to copy kinect (no controlers)? I doubt it.
PS3 and Wii will duke it out for sonsumers but Xbox360 will have it's own market. Therefore, Wii will start to decline (still selling well), and PS3 will not catch up to Xbox360.
If Kinect is mildly successful, then Xbox360 will come in third.
