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.
