Yeah but if thats the case then we might as well have one pred and one alien to balance the fights out because having three preds in this film would turn out the same as the first film two preds die and then one survives at the end.
Alien fans don't want the Aliens to constantly win fights; just to actually fight back
. More Predators keeps you on your toes because there's the possibility the Predator could die. That's more exciting than one Predator who we know
can't die until the end of the movie stomping on bugs.
