1: The Pokéstar Studio logo on a trainer class in S/V
2: In a room in PLA, a picture of what appears to be Adler's possible ancestor.

Other than the second DLC taking place in Unova and references to it, that's all I got lol. I predict a legnds game instead of a remake. Please Gamefreak I'm begging you, if
you can develop a Poket Card Jockey remake, you can
develop a good game. Or PMD or Let's Go that is all we need lol.
Also, the title is a joke, but the theories are real.
