I really really really wouldn't be behind another one. I think each franchise is deserving of its own stories, and when the main theme of a crossover ultimately has to be them kicking six shades of shit out of each other, something has to give. I appreciate the concept is a lot of fun in games and comics, but in a cinematic medium the creatures are robbed of much of their creepiness and threat when you're rooting for one of them like it's a football or NFL game. There is glimpses of solid monster on monster action in the first AvP, and that's enough for me. The idea of more, even by more competent filmmakers, does not interest me quite frankly.
