They all die. Right?

Long time lurker here. I am addicted or perhaps obsessed with this film. They must all die, right? Cos of the impact any survivor would have on the events of the first film. Unless, one of them goes into stasis for even longer than Ripley does after blowing it out the goddamn airlock. Then your sequel could be after the events of A Rez. Which would at least make it easier to forget about staying true to the canon. Although it is only around Saturn, which I hadn't realised, always presumed it was deep space. Just from the trailers, no-one looks in good enough shape to live longe than a couple of hours!
