Well I'm glad that they're at least going to use a jungle, that's where the predators belong, and provides the perfect environment for them to hunt. Also, this isn't a prequel, it's a sequel/reboot. I read some of Rodriguez's original script, and they were originally gonna bring back Dutch from the first film. Guess they had to scrap that idea since Schwarzenegger is too old to do that kind of role, and probably wasn't interested anyway. But anyways, the original script involved Dutch and a bunch of other military people being kidnapped, and taken to the predator planet to fight in arena's like gladiators, and the plot revolved around them trying to escape the planet, while along the way discovering that they had actually been abducted, and handed over to the predators by other humans(the agency from "Predator 2") who were working with the predators in exchange for their technology. So expect the plot of this film to loosely follow that, thus making it a sequel of sorts.
