Pokémon Rumble Blast has been given an October 24, 2011 release date.
The title, a sequel of the WiiWare game Pokémon Rumble, marks the first time the Pokémon franchise sees a retail 3DS game. Pokédex 3D was the first application to be released on the handheld via the eShop.

Pokémon Rumble Blast will feature multiplayer co-op modes as well as a StreetPass feature where Pokémon will do battle with each other.
