Well, in the premise it says the Predator is "doomed" -- so obviously hunting the sole surviving human is meaningless at that point in the movie, the trophy wouldn't matter and neither would the kill. So the Predator is either simply trying to survive, or he is indebted to the human in someway. That's all I can make of it so far. If you're referring to the Predator being "unstoppable" ...well, if he's doomed, he obviously is quite stoppable, and I'm sure he's going to sacrifice himself to save the human chick in the "Queen" battle. If you mean that SHE might be unstoppable, I don't know how to approach that. Both Ripley and Dutch survived "against the odds" in their respective movies (except for the 3rd Alien movie) so who knows. "Whoever wins, we lose." Even she survives, the humans haven't won anything. It's AVP, not AVPVH. They're the main event, we're just the bait. Paul Anderson on Howard Stern said this isn't Freddy VS Jason, there WILL BE a definite winner.
