I cant answer this. The reason being, that as much as Ive alwasy wanted a proper ending to Ripley's story, I kinda also want the story wrapped up in some bigger way altogether.
My thoughts now are that if you bring Ripley back, you need to head in some direction, at least for future films, to tie into what Prometheus added. As much as I felt Alien 3 was a great end for her character, i was always bothered by that film being an ending because there were so many loose ends. So I guess, if anything I want both storylines followed up on equally.
Im not saying I want everything wrapped up with a bow, just that the universe is so all over the place now, I feel like the need to wangle some stuff together.
