I am sure some of you noticed this on the Rayman Legends leak..you are smart. A lot of people have been making a big deal about the cord that comes off the Wii U controller. (Pictured below) Some have gone as far to claim Nintendo was having trouble with the wireless capabilities with the controller so they are switching to a wired setup. It seems like the little mystery has been solved.

“sources familiar with the Wii U say that the tablet has a cable coming out of the bottom of it because it is a dev kit, which currently is only available wired. The wireless version of the dev kits, we’re told, won’t be released to developers until June.”
