Not to mention that Gen VII had a very few new Pokémon.
This news basically kills any hope I had of having new Pokémon USUM (unexplored islands, new UBs), though, if it's a 2018 release.
Wonder where it could take place, though. Anybody remembers seeing something that could hint at the next gen in SM (much like the totem in XY)?
Well, Lillie gets on a boat and goes to Kanto at the end of the game.
