Didn't Swen outright say an expansion was extremely unlikely due to spells being OP and/or difficult to manage in a video game between lvl13-20 in 5e?
I'd rather see them expand on what is already there. Add some new equipment, possibly new companions, or more Dark Urge like origins. I think that sort of thing is more likely, but I think there is a long ways to go. They are still working on the PS5 version and addressing the numerous bugs in the PC release (I still crash about once an hour, if not more). There's also story content that should/could be tidied up some.
If they did, several of the characters have direct ties to Avernus, might be interesting to see some tie in to the Blood War possibly?
It could be a continuation of the ending for some of the characters already
