I hope not. I loved Morrowind, but I don't want to go back in a new game, I'd like a new province.
Same goes for Daggerfall, I'd prefer to see Black Marsh or Valenwood rather than somewhere we've already been.
Seeing not that many have played Daggerfall (I know zero people irl, but many many more Morrowind & Oblivion), and seeing how the game looked at that time, and how things worked in the game at that time...
I'd say visiting Daggerfall would be very very different from the game Daggerfall.
But yeah, I'd also like to see provinces. But that's not gonna happen for an expansion. Only for new games.
Still... what I would want for an expansion would be:
- Something very unique.
- Something that has its very own feel and environment, compared to the original game.
- There has to be a connection somehow to the original game.
