Looks much much better. what does the button by the power button do?

Most likely it's the 'Sync' button. Nintendo may have kept the arduous need to sync the controller. Which now begs the question if Nintendo will let us sync the controller with other Wii U's.

The only thing I'm questioning is why the "U" isn't Blue which we all know is consistent in any logos or icons we all have seen. It would be pointless if it only turns blue if the controller is on. It's what differentiates the Wii from the Wii U

The "3" in the 3DS logo is red.  Though, it is all grey on the back of the console.
