Nintendo say that the Wii MotionPlus accessory, which clips onto the base of the existing Wii Remote, 'redefines game control', by more quickly and accurately reflecting motions in a 3-D space. This means that movement of player's arm should be captured more precisely during games, ultimately making for a more immersive game.
What's more, these control enhancements will be on display when the Wii Sports Resort game launches on July 26, offering a beach-themed follow-up to the hugely popular Wii Sports game. Each Wii Sports Resort game comes packed with a single Wii MotionPlus accessory.
if you want to test it out before then, you can pick up Tiger Woods 10 and Grand Slam Tennis which launch the week before Wii MotionPlus.
Wii MotionPlus is expected to launch in Europe in July.
