According to a scooper for IESB, there may be an upcoming solo PREDATOR film in the pipeline.
"PREDATOR 3 (won't be called that), would be a brand new chapter in the series," says the scooper. "All those rumors about it starring The Rock or John Cena as Schwarzenegger's character, Dutch, aren't true. One bit of a interesting talk is that Sylvester Stallone might be being coaxed to do battle with the new "Predator"."
The scooper also mentioned that the script for AVP 2: SURVIVAL OF THE FITTEST is closer to ALIENS than the original ALIEN VS. PREDATOR.
