With E3 just a stones throw away, and the Wii U being the only big console reveal (for the second time) the focus on most gamers mind. What will the final design look like? How much will it cost? is it really going to be less powerful than the current generation of gaming machines? All these questions are set to be answered at E3. But, thanks to a developer and a camera, we have what could be the final design for the all important Wii U controller. First thing of note are the two analogue sticks. Gone is the 3DS circle pad, in are proper sticks to wrap your thumb around. Also not that there are two new square buttons, one next to the power button and one under the D-Pad. What could they be?
