If you're basing all of your facts on the novels and comics, then you should realise by now that most of us dont' accept that as canon. It's pretty much worthless and the most amusing contradictions have come in the most recent books. You're basing all your assumptions on the books, when you should look at what was shown on screen - which is very little. No, the new portrayals won't be like the books. Even the directors stated that they don't consider those or the games or comics as in any way authentic canon. AlienFan07, two of them got killed in quick succession because those Predators acted stupidly, just like anything else can get killed for that reason. If one had bothered immediately trying to kill it, instead of slowly posturing when it had the thing trapped in the neck, it could have lived.
