A fear or at least, modest concern of mine (which is also an expectation honestly) is that because of the structure of the game, the places we get to see will be pretty limited. It won't be like we're seeing the sword coast region, but that act one will be this region we're in now, act 2 will be Baldur's Gate and maybe the area directly beyond its walls, and act three will be back in the Hells, and one section of hell to boot. The thing that makes this an actual worry for me is that I worry that level of constraint will blunt the supposed epic feeling of the story. Larian has shown themselves to not take the limitations they have seriously when figuring out their story, so it seems far too possible that they'll just try and make a story that doesn't work for the way they're structuring the game.
