>>46152471>Are there any indications that there'll be some more serious postgame support in the future through DLC?Nope, it's very unlikely we'll get more DLC, specially now that the anniversary is coming, since we might get new games.
>Also, are DLC areas purely postgame?Isle of Armor can be accessed at any point in the game after you enter the first big city, if I'm not mistaken, and the levels there increase each time you get a new badge, but they cap at level 60.
And Crown Tundra's levels are always at around 70, so while you can't catch anything there for a long while, you can still explore, get items, and go to a Dynamax cave or whatever, and get high level mons there. Using them makes things shittier, but you can breed them to get their prevos
