Wii U doubles the power of the Xbox 360
A development source has indicated that the Wii U processor and GPU have the potential to be twice as powerful as Microsoft's current console.
The source added: "I've heard [a project designer] complain it's underpowered compared to what Nintendo announced, resulting in people having to de-scale their plans."
All will be revealed when Nintendo brings the finished Wii U to E3 this year.
