Nintendo unveiled the accessory last summer, promising that it would improve the accuracy of the Wii Remote's motion-sensing capabilities to an almost 1:1 scale. At last official word, the add-on was to be bundled with Wii Sports Resort this spring.

When played in conjunction with the MotionPlus accessory, Tiger Woods is said to "allow golf fans to experience a near-perfect 1:1 swing." Meanwhile, Electronic Arts vowed that Grand Slam Tennis is "the deepest tennis experience ever for the Wii," and noted that both Grand Slam and Tiger Woods 10 would eventually hit other platforms.

Those versions of Tiger Woods PGA Tour 10 for other platforms will ship in June, the company added, while stressing that Grand Slam Tennis is "available first for the Wii."
