AvP3 don't work in my opinion because Prometheus made AvP and AvP-R non canon if i'm not mistaken. They should reboot it, not making a sequel. Agree with Queen vs Power Loader round 2 but the Queen should win. Marines should be included and tajes place in the future. Agree with Cruentus to make a reboot, not a sequel to the mess.
For anime AvP, maybe yay. A treatment like Godzilla or maybe Attack on Titan might be work for AvP. An animated AvP series would appease the fans of both series, only if the two balanced, not leaning to one side. You don't want a single Warrior killed a camp of Predators or a Predator blew up a planet single handedly, right?
