Just kind of my imagination running, but what would you think if the jungle hunter wasn't the only predator in the jungle from the first film? Like what if we saw something similar to P2 where there's a clan of Jungle Hunters that were observing and watching and/or also hunting in that jungle. Also what if they made a film that started with a helicopter departing from a obliterated landscape (End of first Predator) and as the camera pans back we see multiple jungle hunters watching the blast, just something I thought would be cool :)
I'm pretty sure Word of God was that JH was the only one, but it would have been really interesting if we were actually seeing 3 of them with only 1 dying.
