Breaking: In a surprising announcement, Nintendo have confirmed a peripheral which will allow for more accurate Wii controls, with a promise of 1:1 gameplay response.

Directly from Nintendo of America, we've just received news of a brand new Wii Remote attachment which will be fully unveiled at Nintendo's E3 conference tomorrow evening: Wii MotionPlus.

The peripheral plugs into the port on the bottom of the Wii Remote and is said to quickly and accurately reflect motions in a 3D space. The device allows for more comprehensive tracking of a player's arm position and orientation and reportedly provides players with "an unmatched level of precision and immersion".

The device will pick up on every slight movement of the user's arm and works in conjunction with the accelerometer and the sensor bar. Games utilising the device will pick up accurate real-time and 1:1 representations of a player's motions.

This news comes just hours before Microsoft is expected to reveal a motion-sensing controller of their own. Let us know your thoughts on this surprising new development in the comments below. We'll be bringing you full details as they're revealed at Nintendo's press conference tomorrow evening.
