Looks like a new Pokémon Rumble (known as Pokémon Scramble in Japan) is in the works for an unspecified Nintendo console. Yesterday, the ACB (Australian Classification Board, the Australian equivalent of PEGI) gave the PG rating to a mysterious game called Pokémon Rumble World. Just like the previous titles in the series, it is being developed by Ambrella.
Unfortunately, we have no way to know whether the game is for the Wii U or the Nintendo 3DS, or if it’ll be a retail or download-only release. All we know is that the game will have some sort of online interactivity. No doubt Nintendo should make an announcement pretty soon, probably during a Nintendo Direct presentation.
Pokémon Rumble World should come out this year, worldwide.
