I don't see xbox one reaching xbox 360 numbers unless Microsoft come up with another Kinect selling type. On the other hand, ps4 might surpass ps3. Ps move didn't have that kind of impact that Wii motion control and Kinect had. Most of the sales were on his own so ps4 can sell on his own as well.
My predictions
PS4 90-100m
Xbox One 50-60m
Wii U 20-25m
