New patent documents for the Wii U's controller reveal all manner of bells and whistles, including a couple that we hadn't heard about.
Sure, it's got a screen; of course it's got a camera. It's got an accelerometer, too, whoop-dee-do. But it's also got flash memory, though how much memory has yet to be revealed. In addition, it's got a magnetic sensor that could be used to detect body motion without a camera.
