Like the last Pokemon Day topic, I'm guessing that we're probably going to get a DLC for Legends, ingame events for BDSP, and maybe Home compatibility with PLA and BDSP. They could also reveal Gen 9 because this the Pokemon Company and a new gen means new mons, new merch and new anime for Ash to wander around in until the next gen. They could also patch for Sword and Shield and allow every other mon to migrate. That's pretty much it what I think/hope for Pokemon Day.
