So what they brought VA's back? It was before the patch 2 so what does it change? And with literally thousands of endings availavble how to you expect them to make a dlc? Or maybe they should add some side story, like phantom liberty from cyberpunk but instead of getting screwed it would allow us to somehow fix Karlach?
Actually, they've been working until way after Patch 2. If it was just voicelines, it wouldn't take that long. But voicelines coupled with motion capture take a very long time. Here's Emma Gregory (Minthara) thanking BG3's voice and performance director as well as the voice and mocap production company almost a month after Patch 2. They're probably still recording stuff with the others, likely for the epilogues.
What does it change? Well, it defeats your narrative that they won't do anything because they don't have to, given that they are doing a lot of things they apparently didn't need to do.
The game having a lot of endings doesn't preclude DLCs. It's the flags that are the problem. Wiring them would be a hassle regardless if it's a side story or not. That's why the path of least resistance for a Karlach fix is an epilogue.
However, Larian almost bankrupting themselves over Divinity and releasing a free definitive edition should tell you that they'll go all out for BG3. Again, that's not to say we'll get what we want, but they're definitely not done with expanding the game.
