Legendary designer and all-around goofball Shigeru Miyamoto discussed the Wii U hardware in a recent interview with Kotaku. When asked why the console won't be able to sit vertically like every other console on the market -- note that both its sides are curved -- Miyamoto said, "I guess we could make a stand," before quickly side-stepping the question and discussing the impetus and design inspiration for the console.
So there you have it, folks: the Wii U won't stand up. Hope you weren't planning on standing this thing on its side. But does it really matter?
