As part of trying to know what this Alien movie is about with all we know... I did a little resum and ideas of every sketch Neill Blomkamp put out there, given the presumption they help him for the year or so worked' story and also help him get S. Weaver and Fox interested.
1.- Location
Weaver has told a lot of times that she didn´t want to go to Earth, and given the fact she like the NB story, we could asume this is happening in a massive WY spaceship or Another Planet installations. But, the title for some sketchs says WY Headquarters... Also, notice almost every sketch indicates the main story could happen here.
2.-Ripley/Hicks
Maybe the most spoiler one. Hicks is not wearing militar signs. They are not the ones from Aliens, they look older maybe the actual age of the actors. This "bomb chest" scene potentially in late stages of the story? could be very stupid for NB to reveal it.
3.-Derelict
Looks like the Alien Derelict, not the juggernaut Prometheus. Also, covered with slime? not making sense, since the slime is for the nest/eggs, and they always are in an inside location. So what could happen to this ship?
4.-Melting
Im using the sketch's title. Ripley is crying so this is one character she cares about... with the Aliens events we know she only has Hicks and Newt to care, but with the older looks of Ripley/Hicks, could be a new character. And... is this an egg evolving? but I can´t see no one... Could be Prometheus black goo? Also, for the yellow lights it looks like it is near/inside the derelict área, so this could be part of the slime covered ship?
5.-Obelisk
From all, this is the one that intrigues me the most. What is that thing?... It doesn´t look like a WY component, looks more like another species tech, but with an ancient/sacred form.
6.-SpaceJockeyRipley
Very spoiler again. 2 options. Ripley goes Kerrigan Starcraft or: Given the assumption this happen 30 or so years after Aliens, WY potentially gain the cappabilities of using SJ tech. The later seems more plausible... also this seems more like a camouflage suit than a Prometheus Engineer human suit.
