Do you expect any returning characters?
So The rookie and Joseph are likely still alive, Jacob and John are both dead. Faith seems to be dead, but that whole section was the most blissed-up part of the game, so it's technically possible that her death was a hallucination (albeit unlikely ofc).
And there were so many bunkers around Hope County that's it's possible that a whole variety of people survived. So who are you expecting may return in New Dawn?
Oh and I'm sorry to break this to you, but Boomer is dead. :(
