Wii U hacked and CPU clock speed revealed, apparently.

[Ail]

Anyway provided the PS4 and the Xbox720 don't go the way of the WiiU by adding a tablet as a remote , they will be able to invest the cost of that tablet into the main console, making it more powerfull than what the WiiU does by comparison.
It's just straight maths, if you don't provide a tablet/controller that cost 80-100$ you can spend that amount on your CPU/GPU...
