Again, it's not about fixing, it's about adding, it's about having the balls and try to break new ground, the best sequels are the ones that add to the mythology, otherwise you get a knock-off.
Predators obviously have a society with the Elders and stuff, and i find that tremendously interesting, there is much potential there for cool stuff. All that great stuff we wouldn't know if Predator 2 didn't add certain elements it, just like with Aliens, the queen... sometimes you gotta have the balls to move forward and either it works or it doesn't.
Shane Black is no Paul Anderson and he said multiple times he wants to make the Predator creepy and mysterious again, even if they show new stuff, i'm sure it will be in line with the character.
Looks like we just disagree on this though, we want different movies and that's ok. For me, everything looks very promising so far.
