Wii U controller raised a few questions when it was announced at E3. Questions like, "What kind of crazy games are going to use that thing," and "How much will a second controller cost me?" The latter, at least, has been answered. Nothing. You don't need one. Nintendo's Satoru Iwata recently said in an interview that games enlisting more than one Wii U controller aren't being considered just yet -- although they are possible. Our very own Ittousai tells us that Iwata told Diamond Online that the Wii U can technically support multiple screen-controllers, but that additional slabs would be too expensive to sell on their own. Iwata went on to say that the console would ship with only one, and that game developers should design titles under the assumption that each console will use a single Wii U controller. Player two will have to settle for a good 'ol Wiimote, and even Satoru himself admits that there are plenty of those around.
