Spore Hero Arena is the new DS Spore game and this one is more focused on battling. The creatures will all be in 3D, which is pretty impressive for the DS, and players can fight each other over Wi-Fi or local play. There will be puzzles and challenges for players to complete, but the main focus is to become the Galactic Champion.
Sounds like Spore Creatures all over again except for Wi-Fi battles. I wonder if they will bother improving the formula from Spore Creatures.
