It's called the Wii MotionPlus - gives the Wiimote the ability to track its position in 3D space. The practical upswing of this is that we can finally have games with 1:1 motion tracking.

Personally, I feel, as cool as it is, I really just feel this should've been included from the start. Oh well, nothing you can do about it now. Can't wait to see games that make use of this, though.
