Well, after all of Mike's hints and the leaks/rumors from V-Scooper on twitter, i think i know where this movie is headed.
So, apparently there was some confusion as to whether the characters will board an abandoned spaceship or a space station, so here is what i think is the secret of the premise.
The characters will board an abandoned spaceship that is currently undergoing Special Order 937.
That is right, i think that this movie will shows us what the next phase of that order was and what Ash was suposed to do (go to).
The abandoned spaceship will probably be on an automatic route towards the Romulus space station, which will kick off the actual second act of the movie.
So what do i think the Romulus space station is, well, i think it's a sort of black site (like some other guy posted here), where Weyland makes secretive research and experiments with alien lifeforms, etc...
The supposed Xenos in cryo-statis (that were hinted by V-Scooper) are probably the organisms that were sent there by command of Special Order 937, through the work of Company androids.
Which means, that the Nostromo crew was simply one of many crews that ended up making contact with Xenos through the Company's influence, with the exception being that Ripley managed to defeat/override it, so Classic Ripley W!!!
The poor young thieves/scavangers of the new movie will try to steal some equipment from Weyland in order to get some money and resources but will end up unleashing their secret cargo, Xeno, so all hell breaks loose.
So yeah, i don't think this movie will have any Big Chap return, sorry
@Nightmare Asylum , but it will expand upon The Company, their nefarious business and show us what would happen if Ash were to succeed in killing Ripley (and the others) and finish Special Order 937.
I think this movie is going to show us what would happen if Ripley failed and died.
Mike said that this movie has a very unique premise and that a lot of people (behind the scenes) think that this movie will be very special and that it united a lot of hardcore fans (from both VFX and practical effects) in order to make this a memorable movie event, so what could be more special (and inoffensive) than to bring back a very interesting plot point from the first movie and expand upon it, without actually retconning anything.
Sort of like what Noah Hawley did with Fargo's first season with the money bag...those that watched Fargo know what i meant.
Mike also said that there will be some sort of connection to the prequels, so they could easily throw some easter eggs such as Neomoprh corpses or the black goo being experimented upon within the Romulus space station, without actually using them as prominent plot points, therefore making this movie a back to basics in regards to ALIEN and ALIENS, without throwing away the prequels completely (for better or worse).
So this could also be an explanation as to why Romulu's facehuggers have some sort of hooks/barb-wired traps on its fingers, and what i mean by that is that they either were experimented on or they were simply from another Hive besides the eggs from the LV-426's Derelict and therefore adapted or evolved in a different way.
Not to mention that Prometheus and Covenant can also be mentioned as Weyland vessels that have made contact with alien lifeforms.
I have nothing to back this up but i am extremely confident about this prediction lmao
