I'm not sure why people seem worried about BG3 "being late" or "releasing at all". That's not their current problem at all.
They are probably doing just fine on that front. At worst the game will take few more months and that's it.

As I said more than once I'd be fairly more worried about WHAT they are planning to release exactly rather then when. And most of the things that could be addressed to make the game better arguably are not even particularly time consuming.
The main requirement would be Larian taking a clear decision on what they want to do with the core mechanics.

Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
