The first movie used horror because the creature was not fully revealed until the end.
The second movie couldn't use that for obvious reasons, so it used action.
The third movie used the equivalent of detective fiction, with some political intrigue at the end.
The fourth used political intrigue mixed with action.
The AVP movies brought in some backstory about the alien and one was set on present Earth.
The prequels used cosmological content and rehashed formulae from the first two movies and the fourth, e.g., armed groups with scientists, a protagonist looking like Ripley, a crew member named "Tennessee" (like Dallas from the first movie), and so on.
Given such, if they set it in present Earth, then it might resemble one of the AVP movies, if not the fourth Predator movie. If it's set in the future, then it might be like the fourth Alien movie.
