In an interview for his most recent Legend of the Guardians film, Zack Snyder talks briefly about the new Superman movie (about 1:40 into the video) and confirms for the fans that the new film will have nothing to do with the other movies.
He seems very reluctant to talk in this interview about Superman. You can tell he starts to get a little uncomfortable when it's brought up. Although I have been wondering where this would fit in with the other movies. Guess that answers that question. Which kind of sucks. I was really hoping to continue that franchise, but I guess it really does need a reboot, and a way to separate itself from the last one (even though I didn't think it was that bad).
