Most people could probably be persuaded to get the Wii U just to play a select few of the "U" titles you're mentioning as a joke, though. :)
Kid Icarus U, Rhythm Heaven U, Baten Kaitos U, Metroid 2D U, F-Zero U, Advance Wars U.
Man those could all be terriffic games. But there's quite little chance of any of them happening.
