Internet reports, an un-named developer of the Pokemon game franchise has revealed that a Pokemon RPG title for the Wii is in the works although it is not yet known whether this will be a sequel to Pokemon Battle Revolution. According to the dev, there has been no Pokemon RPG for the Wii recently as Nintendo wanted to push Pokemon trading on other platforms as much as conceivably possible before handing that over to the Wii.
