I would like there to be an expansion to the Pokemon Mystery Dungeon series.
And they will be for the Nintendo GameCube and the Nintendo Wii.
But that hasn't been confirmed that there will be one.
If you want to change your Pokemon's nicknames, the only thing to do that on the GBA version is to use CodeBreaker and use Nickname Modifier codes for the specified Pokemon.
