FIFA 12 on the 3DS does not feature online play, but will look into in the future

FIFA 12 on 3DS will only have local multiplayer, contrary to the game's announcement press release, which said it would have "head-to-head online matches using Nintendo Wi-Fi connection."

Producer Matt Prior said in a forthcoming Nintendo World Report interview that "Currently, we only have local head-to-head play, but server-based online is certainly something we would be looking at in the future."
