Pokemon Battle Revolution has been revealed as the first Wii game to use DS as a compatible controller.
Instead of using the Wii-mote to select your pet's attacks during a battle, by setting up DS's WiFi connection with the Wii console you'll be able to use the handheld's touch-screen to make your offensive selections.
Also the first game to feature Wii's online multiplayer, Pokemon Battle Revolution is planned as a launch title for Japan, before being released some time next year in the UK.
Nintendo is obviously serious about a feature it attempted to push between GBA and GameCube, with The Legend of Zelda: Four Swords Adventures and Final Fantasy Crystal Chronicles among the only titles to make any decent use of the compatibility between the handheld and console.
With Wii's controllers being less suited to games that don't heavily feature motion-sensitive gameplay, however, a DS could become a useful tool thanks to its easy to use touch-screen ability. We're hoping to see more developers push the unique aspects of Wii, and the link with DS could be yet another innovative strength for Nintendo's new console.
