The highly anticipated film Prometheus, directed by Ridley Scott (Blade Runner), which had intended to be a new story set within the Alien universe left many fans dissapointed, and made the prospect of a second film less likely.
However, when asked during an interview with X-Men: Days of Future Past costar James McAvoy, Michael Fassbender, who played android David in the film, revealed that the sequel is going to be made. At one point during the interview, McAvoy turned to Fassbender and asked, “Are you doing a sequel?” Fassbender responded “Yeah, but when I don’t know.”
