Well at first, within the last 48 or so hours, someone had added up the plot based on the LatinoReview.com synopsis review of the film.
According to an early script review by LatinoReview.com, the plot of the film follows a man named Royce who is abducted by alien creatures known as the Predators. He is released onto the Predators home planet -which acts as a game reserve- along with seven other humans, where they are hunted by creatures known as "Black Super Predators". While battling to survive against these creatures, they also stumble across an American soldier known as Nolan who was brought to the planet years ago as game, but has managed to survive by hiding from the Predators in a cave. Nolan reveals that the Predators have been hunting humans by dropping them on this planet for many years. A cameo appearance is also written in the script for Arnold Schwarzenegger's character Dutch from the first film.
Thats concerning the plot. The parts I bolded which I believe to be the innaccuracies.
1) It's A Predator planet, not THE Predator planet as far as I can recall from the script. From what I remember, it's just a game reserve, a safari planet. Unless of course, I am mistaken since I am recalling this from memory.
2) Minor inaccuracy. There is only ONE BSP, but two other Super Predators.
Now here are the details concerning the developement:
The film was written by Robert Rodriguez, Alex Litvak and Michael Finch. In 2009, 20th Century Fox studio executive, Alex Young, called Rodriguez to consider using his treatment to revive the individual Predator franchise. It was originally thought that Robert Rodriguez would direct, but on June 12, it was rumored that British director Neil Marshall was involved in directing the film. On July 1, 2009, Nimród Antal was officially signed on to take the director's chair. In an interview with MTV, Rodriguez expressed that he wanted his reboot to be the direct sequel to the original, ignoring the Alien Vs Predator sequels.
That part I bolded because three to four, maybe five days ago-- probably going back a week or so, it said on the article: "In an interview with MTV, Rodriguez expressed that he wanted his reboot to be the direct sequel to the original, possibly ignoring Predator 2 and the Alien Vs Predator sequels, saying "Maybe people will forget about the bad sequels and think only this one and the original exist."
So far thats all I could find. I do remember Rodriguez saying that he was omitting Predator 2 and at Comic-Con that he was starting over with a new slate.
