I guess, officially, it can probably be said that there are two timelines currently (but that can split back into three at any given moment, and I'm sure according to some sources it is three, given the split Alien/Predator/AVP licenses). I'd love for the currently existing AVP movies to be a separate thing entirely, just on the basis of not liking them, but as it stands,
The Predator does make explicit mention of them which makes it fair game for them to exist in the Predator canon (for now), while
Prometheus and
Alien: Covenant explicitly knocked them out of the Alien continuity.
Timeline A:Prometheus
Alien: Covenant
Alien
Alien: Romulus
Aliens
Alien 3
Alien: ResurrectionPlus Hawley's series, which should be somewhere around
Prometheus' placement on the list, but we don't have a hard date for that yet.
Timeline B:Prey
Prey 2
Predator
Predator 2
Alien vs Predator
Aliens vs Predator: Requiem
Predators
The Predator
BadlandsBut now, what happens if
Badlands' presentation of the future does line up with what we know in Timeline A/the Alien continuity, or when we do eventually get a new AVP film that presumably tries to bring the timelines back together?
