In addition to the planned talking dolphin game Teo, the Japanese development group is also working on a project codenamed VRS Racer. The game will use the voice recognition unit (included with Pikachu Genki Dechu) which will enable players to give voice commands to control the on-screen action. It is not yet known what form VRS Racer will take, or whether the game will actually let you steer a vehicle.
More on the VRS racer as it breaks.
