I think the post-game epilogue is great as-is apart from the bugs people have mentioned. But I was wondering what they could be working on based on a few of their recent tweets. Since they added new cinematics and scenes for the evil ending I thought maybe they were going to do something similar for the good one, but I didn't take into account that the endings they added are only there for people who are locked out of the main epilogue. Someone with Larian said there was more to come, but I don't think it's anything on the scale of the new ending cinematics now. Probably just photo mode.
