With all that chaotic mess you see some of the mutants in the middle of, maybe they'll use it as a set up to bring Mr. Sinister and Apocalypse into the story. From what I hear, they're talking like it's the last in the franchise. That would be a pity, because I'm getting a little bit sick of seeing Magneto as the main heavy in the films.
This is also supposed to be a set up for the Wolverine movie too. I think at the first of the film, Jackman is being chased by bounty hunters, super powered ones: it can only be either Omega Red (God, one can only hope) Sabertooth, Cyber or a bit more far-fetched, Donald Pierce and the Reavers. Omega Red would be the perfect villain for the movie. Arkady is just too ****ing bad with those "Death Coils" of his.
I love it that they did such a great job on Kelsey Grammer as Beast. Looks exactly like him.
