I demand your predictions!!
Mine are as follows
Wii2 - Wiimote with built in motion+, better speakers, built in microphone, wireless nunchuk with equally good motion sensing, and possibly a speaker as well for surround sound. Support for Wiimotes, balance board, original WM+, nunchuks and classic controller for backwards compatability (hey, they connect via bluetooth so why not)
720 - controlled by a combination of a camera and 2 controllers that are quite similar to what you would get if you sawed the 360 controller in half (ie 2 nunchuks but without motion sensing, and probably more buttons)
PS4 - Upgraded sixaxis, looks extremely similar to the sixaxis but with motion sensing approximately equal to Wiimotion+)
EDIT: I should probably say upgraded Dualshock3. They wouldn't take away rumble again :P
