The Wii U plays games that run on a proprietary 25GB format. That’s the same size as Blu-ray discs. But don’t think that means the Wii U will run Blu-ray discs. Heck, it won’t even run DVDs.
It looks like the product of a fevered fanboy wetdream. A 6.2-inch touchscreen, surrounded by dual analogue sticks and oodles of buttons. Like the portable hardcore gamers wish Nintendo made. But it’s the most incredible controller ever.
