Ridley Scott is developing a new Alien movie following Alien: Romulus' success!

That's good news! I hope the prequel trilogy can be finished by combining it with the next sequel to Alien: Romulus to include David in the sequel to Romulus where Rain and Andy will meet David.

I hope that it has nothing to do with David, I would vomit if David the android is involved.

I would like to see or hear what happened to David for closure reasons

Sir Ridley still has that creative spark it seems, and while it's certainly nice to read about the positive entusiasm from the aged legend, I'll take it with a grain of salt.

If however Ridley decides to direct yet another film set in the Alien universe, and Fassbender is asked and signs up for it, I'm certain we'll see the flute-playing, philosophical android once again. Blade Runner replicants, Raised by Wolves androids and the emphasis on David and his poems about creation; Ridley sure likes his synthetics.

As for the engineers, well they remain a question mark. While hardly fleshed out in Prometheus despite being a core aspect of its grandiose story, it didn't exactly help their lore by throwing them out the window in Covenant. Bam, nuked from the story. On to the next one.

The emphasis seemed to be on David who, while an ambiguous figure at times ultimately turned out to be a classic (and very emotional) world-conqueror villain through and through as he set course for Origae-6 with evil intentions in a grim ending. Now what?

While anything is possible I just hope we'll simply get an entertaining sci-fi horror film from start to finish and with Ridley Scott at the helm again (if he returns) it'll at the very least be a beautiful film visually. Can the magical cosmic horror from Alien and Aliens ever be created again? I believe so considering the masterpiece George Miller created with Mad Max Fury Road for instance. It might take a kitchen full of the best and most motivated chefs who're willing to corporate and encourage each other, but I believe it can be done.
