Not that it would necessarily boost sales but I wouldn't mind a redesigned Wii U, perhaps call it the New Wii U. Here are some things I think they could incorporate.
Smaller/sleaker Gamepad, I really enjoy the Gamepad but it is a bit bulky. Perhaps similar in size to a Vita would be nice.
Increased battery life on Gamepad along with further range from console. Obviously it won't be able to leave the house but currently I can't leave the living room without losing signal. I just want to be able to play off-screen in my bedroom.
Perhaps faster CPU for quicker download/loading times.
Something like this would be nice but with Wii U selling so low, I'm not sure if it's really worthwhile for Nintendo to release a revision. The only way I could see them doing it is if it brought down production costs by a decent margin.
When the herd loses its way, the shepard must kill the bull that leads them astray.
