It wouldn't make sense to make a movie where the Predator dies right away. Maybe the best thing about the original AVP was the fact that Anderson understood to appease everyone you needed both species to kill eachother off. The grid alien does this to the first two Predators. This film is based around 1 Predator. What do Predators do? They hunt, or in this case "clean". The Aliens have great strength in numbers as we see in Aliens. The Predators are very technologically advanced and have distance weapons at their disposal, so naturally the Aliens don't stand a chance in that regard. The Strause Brothers are not Predator fanboys, they just can't make a good movie unless the Predator does what he does best. Besides, even though the entire movie has been pretty much shown already, the Predator almost certainly dies as in the first trailer we see him impailed by the Hybrid's tail. Relax, this movie will satisfy both the people who root for the Alien and the Predator
