Actually there being a main series game around the same time as a (substantial) spinoff has never happened- there has always been at least a 6 month gap.

I think the last post card being of the antagonist is unlikely because the games usually have a “secret” antagonist and revealing it in a post card bundled with the game would be quite anti-climatic. However most of the games have secondary antagonists that pose as friendly creatures from the beginning like Dusknoir or Munna, so it could be Blobgarde.

It could be that Super mystery dungeon will have references to new megas like Blobgarde and Shadowgarde. There are a few pictures of new merchandise floating around where one item is a secret. It’s also worth pointing out that Munchlax and Bonsly were present in XD (although they were unobtainable), and there were statues of Munchlax, Lucario, Bonsly, Weavile and Mime Jr in the original Pokemon Mystery Dungeon games, both of which came out before Diamond and Pearl, so there is a precedent

I agree
Volcanion is just a myth

I just want everyone to know that Chip helped me study and pass my university Chemistry final. This guy is uber smart.

I still have to play Fire Emblem Awakening! I should have bought it last year, but it was sold out when I was intending to purchase. Ah well, it will happen at some point.

I’m going to be broke. Fire Emblem Fates, Bravely Second, and a potential Pokemon Game. Man, Nintendo is just burning my wallet.
