An anonymous developer speaking to Develop has claimed Wii U has twice the power of Microsoft's Xbox 360.

The source said Nintendo's next console boasts twice the processing and graphical output of Microsoft's 6-year old console. Of course there are no statistics to back this up, but if true, it would represent an enormous leap over the Wii's current power.

That said, some developers are apparently displeased with the console's power, and have had to scale back some of their plans, in a prime example of the industry term "can't please everyone".
