EA announced today that they will be developing a Wii minigame multipack (like Wario Ware) game. Titled EA Playground, the game will feature many minigames that deal with the motion sensor (in other words, a get up and move around game).
So far the list of games include: dodge ball, RC racing, and a game like Tether ball (ah yes, classic school playground action). Also announced is a version for the DS as well. This game will incorporate the microphone and touch screen in a bunch more minigames.
It should be releasing sometime this fall.
