Wii U hacked and CPU clock speed revealed, apparently.

I don't think its fair to say that what we see now is the best we'll get, especially since 1st party offerings are ported Wii games, and 3rd party offerings are hastily ported 360 games.

Remember during WiiU development, Nintendo and many 3rd parties made comments about how Nintendo built the WiiU to fit their requests. Gearbox was especially positive on the WiiU during development. And the Trine 2 devs have said that they would have to take stuff out of the WiiU version to get it to run on the 360 or PS3. There is more here than meets the eye, for certain.
