A listing on Amazon.de for "EA SPORTS Grand Slam Tennis + Wii Motion Plus" bears out CubeRevolution's claim. It appears that Nintendo really is allowing EA to bundle its first-party accessory with a third-party game in Europe this July. Amazon even took a few Euros off the price!
While it's great news that people might be able to buy a MotionPlus in July, and with more bundle options, we can't help but entertain the theory that this option frees Nintendo up to delay Wii Sports Resort past the summer.
