One of my main concerns about the Wii U is that it has the same controller-syncing problems that required lots of one-button manual recalibration of the Wii Motion Plus Remote in Wii Sports Resort and The Legend of Zelda: Skyward Sword.

The problem is that the Wii U sometimes wants you to point the GamePad at the TV, but the GamePad doesn't have a Wii Remote-style pointing sensor. So, the gyro sensors in the GamePad have to calibrate a center position and then try to help the Wii U to remember that relative center point. Before long, it fails to track accurately.

Watch the video to see how that goes, and note that it is not a fault of the gyro itself, which in several Wii U games I played today is easily able to understand the tilt and rotation of the GamePad. It just can't remember it's relative position to a TV very well.

The video here should make this clear.
