Yeah, but the first Predator literally busted a cheap move and tried to blow everything up because he lost. I get the feeling these Predators don't exactly play by their own rules which have never been laid out clearly anyways.
After Black's statement about the AVP, I lost faith completely.
I think he's trying to not alienate fans of avp but still saying his film wont acknowledge those movies.
He said there won't be any Xenomorphs in the movie, he's just saying AvP "happened". I doubt the movie will acknowledge it much with any dialogue.
