What the interviews on RPG Codex and RPG Watch said didn't really make a lot of sense when it came to SP so I am waiting for that update too.
I can safely say that if the companions are anything like in D:OS then this will make D:OS 2 a skip for me... but that's fine. No dev has to cater to my needs

It would just be nice if Larian came back to it's SP roots and actually implemented a system that is first and foremost there to make SP great, and not just COOP.
Edit. Guess I have to add, but to me "great" means immersive writing, character development spanning the entire game, and interesting well developed companions that disagree with me when it makes logical sense in their writing, not because I lost rock paper scissors....
