If the way they supported their previous games is anything to go by, I wouldn’t expect any DLC. there was no DLC for divinity original sin or D:OS 2. This is the game, if you want more of it you start a new run, maybe on tactician mode, with new builds.
I agree! To continue the argument: DOS2 was, at the time, a big hit for Larian. Its one of the main reasons why they could expand the way they did. I think that the way Larian does development is not very conducive to creating DLC. If they do, I suspect it will only be released at the end of 2024 at the earliest.
