I've thought for a good long while now that a historical setting for a Predator movie would be both awesome to see, and a wise choice from a franchise perspective! The predator seen and experienced through the eyes of historical peoples who have no frame of reference for aliens/UFOs will make it feel fresh and different without taking the tired old "bigger, better, badder" route. I both hope and assume there will be actual native consultants to ensure the portrayal is accurate and inoffensive (Hollywood doesn't have the greatest track record in this department!) and so, if all goes well, we could be in for a great and interesting movie.
