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.

You know another thing magnets are good for detecting? Heartbeats. So it's poooossible that that magnetometer marks a sneaky return of the yet-to-be-released Wii Vitality Sensor.

I'm just saying. It sounds suspicious.
