My concern is if they are on the predator planet, they will most likely kill off TONS of predators so the heroes can survive. Or have them sneaking around in it which will also suck because the predators would obviously know they were there. This is not looking good so far.
I still wish they did a story of a bad blood predator with an elder chasing him down. Something along the lines of we see the bad blood kill predators on his homeworld, then he flees to earth where he kills all he sees without honor (like children, injured people, ect.). Then the predators send an elder predator to hunt him down and the have a crazy battle at the end where the elder wins and lives then goes back home.
