I think with the way the internet works now, the way pre-release marketing cycles have shifted, and the fact that Romulus isn't some huge mysterious event film sort of RETURN like Prometheus was (both for Alien as a brand, and for Ridley Scott to sci-fi in general), I wouldn't expect anything like that. Something like "Alien: Harvest" feels very much like the product of a time that we don't really exist in anymore.
