Is Marvel now taking steps to fuck with Fox Studios?
Fox Studios has the rights to the X-Men and all the various mutant characters, whether they use them or not. They're also making a new Fantastic Four movie. You might have noticed that even though Quicksilver (who appeared in the last X-Men movie, sans his codename) and The Scarlet Witch are mutants, they had a cameo in the last Captain America movie and will be in the next Avengers film.
So what has Marvel been doing? Well, one could look at all this as coincidence,
but--Marvel did next to nothing to promote the last X-Men movie. No merchandise tie-ins, no nothing. Anything you saw was Fox.
-Wolverine is being slowly killed off. They took away his healing factor (which the Wolverine movie did, too, leading to speculation that it was a tie-in to that, but he got his powers back by the end of the film) and there is a now mini-series about to end entitled "The Death Of Wolverine."
-The Fantastic Four comics are being canceled next year, which is when the film just so happens to be coming out.

Some cite low sales for this, but the comic sells about the same numbers as Captain America, which you'll notice was just recently a movie.
-Marvel has been trying, in their comics, to make the Inhumans a big thing. From what I can tell, it's been kind of a failure. The Inhumans are a group of weird mutant-like characters that used to live on the moon (it's comics...roll with it) but now reside on Earth. They recently did an event where this weird "mist" changed a large number of humans into Inhumans. They are trying to treat the characters just like how mutants get treated (I.E., racism) in the comics. A film is planned for 2017.
-There is now a new comic event that was just announced called "No More Mutants." The teaser image shows...
Quicksilver and the Scarlet Witch.

There is speculation that they are going to be de-powered and then re-powered as...Inhumans. And now that they're not mutants...HEY! Marvel can use 'em in films!
So now this has me wondering about Wolverine. Are they possibly killing him off...so that they can resurrect him as a non-mutant?
And if you're wondering about Spider-Man (Sony Pictures has the rights), apparently Marvel and Sony have a much better relationship.
