Then how come we have so many X-Men related books right now?
If movie rights are Marvel's bottom line then how come they are still publishing the likes of Deadpool? Why are FF concepts and characters playing major roles in books like The Ultimates, Inhumans, Guardians of the Galaxy, the various Iron Man and Spider-Man. Heck why is there Spider-Man books since Marvel the only shares the movie rights to Spidey.
You keep bringing this up as a big "Gotcha" moment when I'm not denying that Marvel not owning the movie rights is a factor, they are going they are going to consider a multitude of things that affect their profits, it's a business go figure. What I am arguing is it's not as big a factor as people think.
