After having just seen the film, my personal take on it is that the Classic Predator clan, while still very violent, fights for honor (in a sense) and sport, coming and taking on its prey in the element it discovers them in. The SPs, which I believe to be a different species altogether but evolved along similar lines, are far more barbaric and brutal. It would not surprise me if the SPs actually stole technology from the classic preds. The SPs used very basic weaponry and booby traps, while in Predator 2 (and the AvP series, if you want to count those as well) we see the Classic clan use more and more advanced weaponry. If this is the case, even if the Super Preds didn't steal their technologies from the Classics, then the Classic's technology could have developed much farther along, allowing it to hack into the systems with relative ease. Something else to support my theory that the classics have superior technology is that (i'd assume) the SPs could see each other while cloaked, but Berserker could not see Classic when he cloaked...
