The game will include the previously announced Wii MotionPlus accessory, which improves the precision and accuracy of the Wii Remote.

Nintendo's Cammie Dunaway demonstrated the game and accessory on stage at the company's E3 2008 press conference, where a number of the game's activities were shown off. Wii Sports Resort includes such activities as the fencing game Sword Play, the jet skiing game Power Cruising and a frisbee toss game known as Disc Dog.

The Wii MotionPlus accessory drastically improves the accuracy of the Wii Remote, and appears to bring 1:1 motion to the hardware rather than relying on the Wii Remote's infrared pointer.

Both the game and the Wii MotionPlus attachment are due for release in the spring of 2009.
