Over at Bleeding Cool, Rich Johnston has rightly called attention to what seems to be a disturbing trend by Marvel to downplay references to the Fantastic Four in all of the 75th anniversary promotional materials. Johnston suggests that the underlying reason is that Marvel (Disney) may be waging a covert war against Fox, who controls the rights to X-men and Fantastic Four. (Unlike the Sony Spider-man deal, Marvel does not benefit from merchandising in the Fox deal.)
Notice the complete lack of FF and X-men references on the 75th Anniversary poster (and logo)
When was the last time you saw a Marvel promo poster that didn't feature Wolverine? Instead of The Thing and Storm, we have Iron Fist and Ant-man. The inclusion of the Ant-man, Guardian's of the Galaxy characters and Iron Fist is clearly meant to work with their upcoming movies and Netflix show, but some others are a bit harder to explain. (Black Bolt, Ms. Marvel, Nova) --- unless there are upcoming movies for those properties. I think I have heard some mention of an Inhumans movie.
Still, outside of the conspiratorial Hollywood games, is it reasonable to think Marvel might cancel (or at least bench) The Fantastic Four for a while? I think so.
For one thing, the property was just recently, re-relaunched (in the wake of a prominent Marvel Now relaunch) with writer James Robinson. And while Robinson's star status isn't what it used to be during his Starman heyday, he's still a writer with some marquee value. Unfortunately, his turn on Fantastic Four isn't really producing much better sales than Matt Faction's was about a year ago (when it was decided to relaunch the title.) As the number crunchers at ComicsBeat put when reviewing comic sales for April...
No re-order activity and sales continue to drop. Fantastic Four will
probably drop to its previous sales low of 28k within a few months...
I don't blame Robinson for this. The list of writers who have worked with the Fantastic Four in some manner over recent years is like a who's who of modern comics:
Brian Bendis (Ultimate FF)
Warren Ellis (Ultimate FF)
Grant Morrison (Fantastic Four: 1234)
Now, in the past, it would have been unthinkable for Marvel to not publish (what many consider) to be their flagship (spiritually, if not financially) title. However, Disney doesn't really care about that. As I've said several times before, Disney doesn't concern itself with printing its own comics. It licenses many of its successful brands (Donald Duck, The Fairies of Pixie Hollow, The Disney Princesses...) to other publishers.
With Marvel things are different. I suspect Disney takes more objective (harsher) look at failing comic titles than past Marvel Editorial regimes.
I could easily see the combo of no money from movies or merchandising and poor selling comics could definitely resulting in at least a temporary hiatus.
