Both titles are slated to hit retailers in June. Red Faction: Guerrilla arrives in PlayStation 3 and Xbox 360 form on June 2 with a PC release later on, while Tiger Woods will hit PlayStation 2, PlayStation 3, Xbox 360, Wii and PSP at some point in the month.

The Red Faction: Guerrilla multiplayer demo is slated to arrive on PlayStation 3 later today, and don't be surprised if the Tiger Woods demo hits PlayStation 3 soon.

Electronic Arts' first two games to take advantage of the Wii MotionPlus accessory will now arrive alongside the optional add-on on June 8, the publisher announced today.

Previously, the Wii editions of EA Sports Grand Slam Tennis and Tiger Woods PGA Tour 10 were slated to launch on June 16. Both games will be available individually at $50, with a $60 Tiger Woods bundle packing the regularly $20 accessory.

The Tiger Woods bundle will be available in both North America and Europe, with Europe also set to receive an EA Sports Grand Slam Tennis/MotionPlus bundle.

Announced last year, the Wii MotionPlus accessory plugs into the bottom of the Wii Remote, providing "a true 1:1 response" for motion controls in compatible games.

Electronic Arts today announced that EA Sports Grand Slam Tennis and Tiger Woods PGA Tour 10 will hit Wii on June 16, and confirmed that the two will the first Wii games out of EA that support the upcoming MotionPlus controller add-on.

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."
