We already gathered that Nintendo’s Wii MotionPlus controller add-on was somehow tied to the launch of EA’s Grand Slam Tennis game, but it now looks like the two may be not just swell pals, but bestest buddies. According to a listing over on Amazon.de, the add-on will be available in a bundle with the game (in Europe), which will cost you just over $70. It launches on July 2nd.

Joystiq speculates that the move could also be the excuse Nintendo has been looking for to delay its Wii Sports Resort game, which was supposed to come bundled with MotionPlus.

Control Freek has a new and unique tennis racquet that aims to prevent sweaty palms by including an air-conditioner in the handle. I suppose this is big news for the Tennis world because sweatty palms will lose you matches and hurt your grip.

No batteries required. It was specially designed to capture air in the handle every time you swing the racquet. That air comes out through the holes and onto your palm, hopefully improving your game. I’m not sure that this would work, but if you’re the sweattiest palmed Player on the court it will cost you $275 to cool off.

Let’s say you’re riding your bike around town and suddenly you have the urge to launch tennis balls at something or someone. Thanks to this inventor, you can satisfy that urge and launch away. It’s completely eco-friendly too, built from two recycled bikes, scrap steel and wood, even a leaking water jug and a lacrosse stick.

Pretty simple but genius way to make a tennis ball launcher. As you pedal the bike, you power 2 other bike wheels that launch the balls. Perfect if you like to ride your bike to the Tennis court. Or just blast pedestrians and the like.
