There are many things that can be done to adjust the hieght and width of the Predators. In Resident evil 2 they crunched Nemisis to make him look bigger. You can use camara angles to make them seem bigger then they actually are as well as pulling off what they did with Gandolf in LOTR and have them simply stand on elevated terrain or film them seperatly and insert them in later enlarged. I know i shouldnt mention AVPR but the pred alien looked like some form of alien midgit in set pics but in the film it seemed big and nasty. So lets just wait for the trailer at least people.
