Will every new update require a new savefile? If yes, could we eventually get a list of avaible Shadow Pokémon and their location (even if later on)? This is just so I know I didn't miss anything between versions. I'm still in the start for now, I'll probably beat the game once before I update, since I soft-reset a few time for some early on stat rolls.
EDIT: Could we also get a list of PokeSpot Pokemon?
