A television show was rumoured in the nineties, but from what I remember, was abandoned because of the projected budget. It's much more plausible for something like that to be done right, though, these days.
The concept art looks nice. No idea what the story could be, but judging from the injuries, that's the original Hicks, no question about it.
I wouldn't be averse to retconning the third and fourth movies as dreams. The third, expecially, has some fairly dream-like qualities about it and we might even get a continuity explanation for the magically appearing egg and why the cryotubes look like those on the Nostromo, instead of Sulaco.
The problem is, it's a huge gamble. If the writing's there, brilliant. If it's off, then all you're doing is replacing one sub-standard branch of continuity with another.
I liked 'District 9', but it wasn't devoid of problems. Unfortunately, 'Elysium' showed what he'd do with a decent budget and it just felt like a bland vanity project. Even the central theme made no sense: If you're keeping the citizens of Earth as a manual labour force and have the ability to heal them of all diseases/injuries, then you do that. The two things you want in a work-force are for them to be both physically healthy and not having every reason to launch a rebellion. The story abandoned that logic as an excuse to do a cheap class warfare narrative.
So, I suspect the story might be as vacuous as that, but I'm open to being pleasantly surprised. After all, 'Isolation' had a story which was paper-thin and was all about the atmospheric presentation.
