While we don’t have a firm release date yet, we do know of a few other changes we can expect to see in the smash-hit mobile game from Niantic and Nintendo. > The forthcoming gameplay changes have been outlined in a post on the Pokémon website. The changes include an update to Pokémon migration patterns, meaning we’ll see different Pokémon by our houses soon. There will also be a greater variety of Pokémon found at places marked as parks and nature preserves. Additionally, weather will have a decreased impact when it comes to spawning new Pokémon.
