All that means, is that Pokemon Platinum can connect to PBR. To my knowledge, there has been no update-patch or any such thing for PBR containing the Plaitnum Pokemon-forms (especially since I believe it would pretty much be impossible without releasing a new version of PBR; PBR has no built in functionability to allow for updates or patches, and Platinum shouldn't have the space on it for the updated sprites and such to send to PBR).http://bulbapedia.bulbagarden.net/wiki/Pokémon_Platinum_Version#Connectivity
"[Platinum] retains the same compatibility with Generation III games, Pokémon Battle Revolution and My Pokémon Ranch (Japan only) as its predecessors."
Maybe NOA will have the same thing happen here?
