Nintendo today set a date for its MotionPlus add-on for the Wii. The device by itself will ship on June 8th for $20 and will let any supporting game get much more precise movement tracking through 3D space, including rotation, by adding the peripheral to an existing Wii remote. Its signature launch game, Wii Sports Resort, will ship on July 26th and will come bundled with a MotionPlus adapter for $50.

The company hasn't made mention of third-party games with the announcement but has previously promised that others are coming in the near future.
