Damn it, wrong button. Here's it completely: The Aliens probably won't win, because the story is set before the Alien saga, and in the Alien saga, earth is still a planet inhabited by humans. If the Aliens would win in AvP, then earth would be inhabited by Aliens, NOT humans. Well, we know one Predators is left with Lex. Will this Predator survive? Probably not. I think he will sacrifice himself for lex or he is just destroyed by the remaining queen or/and Aliens. I think Lex will survive alone, taken with the Predator ship (that is probably controlled by predators inside the ship) in the galaxy far, far away... :p
