“I can't give any details at the moment, but we're working on a new Wii game. We should be able to announce something before long.”
-- Tsunekaz Ishihara
It is unknown if this will be another WiiWare game, such as Pokémon Rumble, or a battle simulation game, such as Pokémon Battle Revolution. So far, there has only been one Pokémon game for the Wii sold on discs while there have been five WiiWare games released, only one of which has been available to users of non-Japanese Wii systems.
