We're not going to spend a lot of time rehashing the basic points of this argument, because we've been over it many times before. Essentially, it boils down to one simple argument: Marvel makes a lot of money on their big title movies, and wants to continue doing so, while actors and studios eventually tire of the increasing commitments. While everyone from Hugh Jackman and Sam Raimi to the parking attendant guy at the Fox Studios lot may think they know for certain the future of their franchises, we all know the truth is very basic: if they feel the monetary benefits are great enough, they will roll out more movies. If they don't, then the movies are done.

So what do Marvel, Fox Studios, and Sony Pictures think about the monetary prospects of more films? Well, according to X-Men Film News, the opinion is different depending on who you ask. Marvel, of course, is hot to sell as much superhero as they possibly can. Times are very good for the company, and their properties are as hot as ever. Nobody knows when the hero movie trend will die down again, and Marvel needs to strike while the iron is hot. Sony, it seems, is in complete agreement, and thoroughly expects to make bazillions of dollars on the third installment of the successful Spider-Man film franchise. This naturally leaves them very open to the possibility of more movies, because hey ... who doesn't like making a bazillion dollars? Fox, on the other hand, wasn't so confident in their third installment, hence the "this is the last film ever" talk from the studio. But then the movie raked in some serious cash, and suddenly Fox might want to reconsider.

Even should Fox decide they are done with Professor X and his gifted youngsters, this won't necessarily mean the end of the X-Men on film. A Marvel insider reminds X-Men Film News that Marvel is aggressively pursuing their own business interests these days, and certainly has plans in place for the team if Fox bails. Tipster says to expect a "pleasant surprise," but what else would an employee say?
