Nah, I think the predators are getting bored of hunting simple lifeforms and have decided to mix one of there own's dna with Arnold's dna, thus the upgraded predator is born. Of course it's totally out of control, a cigar smoking one line chomping bad ass that just wants to lift meat. No rhythm, no reason, it just desires to lift heavy things. The predators are here to steal the sacred vhs tapes in hopes of finding a way to stop the ultimate predator. Least do they know, he's already hot on their tails. Probably steps out of a chopper and says, I'm BACK bitches.
