you must not have played stasis inturupted
I haven't played it but i know all about it. The way they shoe horned Hicks into that game was contrived and senseless. It didn't further the plot or serve the story, it was just done for the sake of it. Just so people could go "ohhh hicks is back, yeah!". If they could come up with a novel way to reintroduce him to the series that's actually integral to the plot and not a blatant attempt to appeal to butt hurt fanboys I'd be all for it.
Blomkamp loves the metaphor of using an 'IMMIGRANT' as an 'ALIEN' and stressing that feeling of alienation... This makes me think he will certainly go with the Ripley 8 clone. A:R largely ended on that note when Ripley 8 states 'I'm a stranger here myself' she is stating that she has literally become an Alien to her own humanity and from her home 'Earth.'
I am thinking Blomkamp loves that idea.
Considering this^^^ and then taking into account that some time would have passed b/w A:R and Blomkamp's ALIEN: XENO, I can only assume that we will find Ripley as an alienated loner, at complete odds with the human race and possibly in existential crisis.
That said, if I had to guess, I'd maybe go with Ripley 8 having something to do with Hick's cloning, in an attempt to find some kinship/test her attachment to another human?.. And of course, go all kamikaze and blow up Weyland Yutani headquarters together.
