Nintendo Japan is teasing a major Pokemon reveal for next Tuesday, though it's anybody's guess what the publisher will be announcing.
Pokemon White 2 and Black 2 arrived last fall in the U.S., while Japan received another entry in the Pokemon Mystery Dungeon series, Magnagate and the Infinite Labyrinth. Previous Mystery Dungeon games have made their way to the states, so there's a chance Nintendo's announcement next week could just be the Western release of Magnagate.
Of course, there's also a chance Nintendo could have something much bigger in store. The Wii U has been absent a Pokemon title since it was released, though a reveal that large would usually be reserved for E3.
No matter what Nintendo's plans, we won't have long to wait until we find out just what's next for the Pokemon franchise.
