Under Disney the franchise still has hope because the first Predator, Alien, and Aliens were all pretty big blockbusters for the time. The might see those figures, take a couple of years to see if rebooting or continuation is the best way to go (it's rebooting guys I'm sorry) and go from there.
There is also the whole disney doesn't do rated r movies, they have a studio that releases r films that is owned by them (can't remember name) that they might be trying to move all that under as well.
Or maybe they are looking for buyers.
Might take a couple of years but I seriously doubt that the series is done with.
One could look at DH at present time retaining the titles in the eu as a sign that they DON'T want to keep the films, since they pretty much instantly shut down DH and SW after they signed it over so Marvel could distribute new EU stories.
