I don't think we're gonna get "generic Predators" at all in this. Black had the whole crew looking back at the original film first and foremost for reference, and obviously that includes the original Predator, and there's this bit of the JoBlo/Collider interviews were he says something that really peaked my interest; he says that he chose to go with misfits for his characters and tried to find thematic elements that worked with that for the movie, and that maybe there's a sense that the Predator himself is an "outcast". I think Black is approaching the Predator in this film as a character, with an arc, rather than just a monster. I doubt anyone's ever topping Kevin Peter Hall, after all he CREATED the Predator body language, but I don't see this movie going with generic Predator performances.
