Nintendo announced the Wii MotionPlus today, ahead of their E3 press conference tomorrow. The Wii MotionPlus is an accessory that attaches to the bottom of the Wii-mote and enhances gameplay ‘by more quickly and accurately reflecting motions in a 3-D space.’ Very little else is known about the accessory as of now. So far it seems like it just makes the Wii-mote more precise. Read the full announcement below and we’ll have more details from E3 this week.

Nintendo’s upcoming Wii MotionPlus accessory for the revolutionary Wii Remote controller again redefines game control, by more quickly and accurately reflecting motions in a 3-D space. The Wii MotionPlus accessory attaches to the end of the Wii Remote and, combined with the accelerometer and the sensor bar, allows for more comprehensive tracking of a player’s arm position and orientation, providing players with an unmatched level of precision and immersion. Every slight movement players make with their wrist or arm is rendered identically in real time on the screen, providing a true 1:1 response in their game play. The Wii MotionPlus accessory reconfirms Nintendo’s commitment to making games intuitive and accessible for everyone. Nintendo will reveal more details about the Wii MotionPlus accessory and other topics Tuesday morning at its E3 media briefing.
