I do hope for
fixing the engine + live togerther with Tav good ending
, but this will not probably be the case.

One month after the release it looks more like polishing actual ends with
avernus to be more good. Lets say few sentences when Karlach and Tav killing demons and looking for cure or something like that
preparing for example for some kind of complete Avernus DLC or definitive edition.

or maybe I'm completely wrong and it will be something completely different
