The guy from MS who said that WiU is little more than a 360 is correct.
Kinect sold more 360s than 3D did for the PS3 or 3DS.
PREDICTION: Kinect will sell more 360s/720s than an extra (controller) screen will for Wii-U.
The extra screen WILL NOT sell the Wii-U.
PREDICTION: Not a single 'assymetric gameplay' game will hit 10M or 20M.
Nintendo has absolutely no idea what they're doing. A year in and we're already seeing the 3DSXL. Desperation. 2D Mari-U will do no more for WiiU than MK7 did for 3ds. The extra screen will hardly be used after the first year, maybe Nintendo will keep using it but 3rd parties will prety much drop it for it's GAMING features.
If Nintendo wins next gen it will be because Sony and MS completely eff up. Sony's nearly out of here but MS should win if they don't focus on Kinect and continue appealing to the PC gamer.
PREDICTION: If Wii-U has a 10M or 20M seller it will be because of motion control or symmetric local multiplayer.
Don't Play Stationary 4 ever. Switch!
