Nintendo slapped us in the face with the announcement of a new Pokémon Mystery Dungeon, set to release in early March.
Well, it's not as big of a deal as NSMBU Deluxe (sold ~750k retail copies in Japan so far), but it's also notably more important than Tokyo Mirage Sessions.
Shipped+Digital was 860k at the end of September so probably ~1 million through December.
Mystery Dungeon will be lucky to sell 1/4 of that lifetime.
