Nintendo has announced the Wii MotionPlus, a Wii Remote accessory that will allow the device to track motion more quickly and accurately.

The announcement comes ahead of Nintendo’s Tuesday press conference, as well as Microsoft’s Monday E3 conference. It has been heavily rumored that Microsoft may unveil a motion-sensing peripheral for the 360 at this year’s E3. 

According to Nintendo, the Wii MotionPlus accessory will combine with the Wii Remote’s built-in accelerometer as well as the Wii sensor bar to create more comprehensive position and orientation tracking. This will provide a “true 1:1 response in game play.”

More details on Wii MotionPlus will be forthcoming at Nintendo’s E3 press conference on Tuesday.
