Nintendo keeps controls simple for the GameCube port in an effort to entice Wii Sports Tennis players.
Details of the latest Play It On Wii title have emerged from Japanese online magazine Inside-Games. Mario Power Tennis (known as Mario Tennis GC in Japan) will be released in the Japanese market in January 2009 and will sport a new control scheme to take advantage of the Wii's motion controller.
Much like Wii Sports Tennis, players in Mario Power Tennis will swing the Wii Remote in the appropriate direction to achieve forehands and backhands. Slices and topspin will also be executed via motion whilst the game's special attacks are made with the A and B buttons.
Nintendo clarified that this version of Mario Tennis will not be compatible with any regular control-stick controllers, meaning the GameCube and Classic controllers are off the cards.
Nintendo must be hoping to capitalise on the huge success of Wii Sports, which is not included with the Wii console in Japan and boasts an almost 1:1 tie ratio in sales.
A North American and European release is expected, however there are no final details of a release date as yet.
