I think Larian got the message about endings, Swen addressed this himself it seems according to this article. Like people have been saying, just give them some time.

To quote Swen from this ^Article^,

"We are adding in extra epilogue stuff. It’s actually underway. Actors are being recalled, writing is happening on that."

"Yeah, we said that we’re going to. We have a tool that allows us to render permutations of the videos that you look at. These videos of the ending were like 18 minutes long. We said, “that’s getting really long guys, this is gonna be going on like the end of The Lord of the Rings.” So we said, maybe we should trim it. And that was a mistake, clearly, because a lot of players were upset by that. They actually wanted that. So Peter Jackson was right."

"So we learned from that. We brought back Sam (Béart), who’s the actress for Karlach right away. She went into the studio, I think, within the first week. We said okay, let’s give an updated ending. An optional ending, because they are all the other ones for Karlach. So we are adding in extra epilogue stuff. It’s actually underway. Actors are being recalled, writing is happening on that. But it’s not (cut) content that existed; it’s something that we are going to create new."

Recent video of the voice actors together all at once, finally.
