I kinda want them to change up the usual. Normally we get a snowy cave or a snow area at the end of the game and I would love if they change that up and let us start with it. I don't know what region in the world that would fit. I also would like to see more swampy areas. Also I would like some more water routes, I really missed them in Alola. I know some people aren't a fan of them, but with the big amount of Water Pokémon, I would love, rivers, lakes and a beach area to be part of the area with a lot of room to surf. And also have different Pokémon available in each of those areas.
Also I hope the Pokémon Go mechanism of catching Pokémon won't be part of the main catching, but will be the new way of encountering Pokémon with a rod. It always felt stupid to me to have a rod, encounter a Pokémon and then having to call out one of our own to battle it. They could expand this, by re-adding the honey feature of Gen 4 or having us hang down a net at certain trees and also implement that Go catching feature there to encounter certain bug, grass Pokémon etc.
And I hope the region is closer to Kanto/Johto/Sinnoh, and adds more cross gen evolutions, some regional forms for Gen V, VI & VII Pokémon.
