The rumor mill has started again. NeoGAF user CubeRevolution announced that EA plans on releasing a bundle including Wii MotionPlus with EA Grand Slam Tennis.
There’s a listing on Amazon.de for “EA SPORTS Grand Slam Tennis + Wii Motion Plus” that would seem to validate the rumor. The price is listed as 53.99 Euros, which is only 10 Euros more than the release of EA Grand Slam Tennis alone.
If this is true, it means that Nintendo is allowing EA to bundle the first-party accessory with at least one of their games. Look for the release this July, if it turns out to be true!
