Nintendo looks set to take the motion-sensing controls of the Wii console to new levels of precision and performance, finally announcing a release date and price for its MotionPlus accessory. The device itself will be out on June 8 with a price tag of $19.99, though you could wait a few more weeks until July 26 to pick up Wii Sports Resort for $49.99, which comes bundled with the accessory.

The adapter will attach to the bottom of the Wii remote to increase the sensitivity and accuracy of its motion sensors to an almost 1:1 scale – jet skiing and fencing are among the mini-games included in Sports Resort to show off the enhanced precision. Several other third-party games have also announced support for MotionPlus, including Ubisoft’s Red Steel 2, EA’s Tiger Woods PGA Tour 10 and Sega’s Virtua Tennis 2009.

Personally, I’ve found the Wii only mildly entertaining once the novelty factor wears off, mainly because its motion-sensing controls offer limited functionality in some games – Wii Tennis for example is nothing short of a joke compared to tennis games on rival consoles. Hopefully this adapter will come as a blessing for those games where accuracy have been off a step or two. Do you plan on getting one or feel the controls are just fine?
