There’s another interesting article on Den of Geek where they’ve analysed the past several years and attempt to answer whether or not Alien 5 will ever be made.
“And yet that hasn’t stopped speculation, rumour, and occasional hints of substance from circulating. Because Alien 5, ideally, would see either Ridley Scott or James Cameron returning to the series. It could explore the alien homeworld. It could see an alien visit Earth (done properly, although Sigourney Weaver in particular isn’t keen). There’s so much of the backstory of these creatures that’s not been explored, and plenty of places the franchise could go.”
It’s a very good article even if it’s just fan speculation. They mention towards the end that a Ripley-less movie is a potential direction for the franchise to go. That it could be a prequel of sorts. That’s been my preference too for many years. Thanks to Darkoo for the news.
