A Mandalorian-esque Predator show would rule, following one Predator on different hunts on various worlds. Could be neat.
Personally, for a Prey sequel, I'd like to see more of Naru's journey. We've seen her become war chief, I'd like to see her learn to be a leader. Like in Prey which contrasts Naru's development as a hunter with Feral's you could also contrast Naru becoming a leader with Greyback. Do something none of these movies have really done and make a Predator a protagonist.
