I think this article offers two potentially promising developments in terms of getting the FF back to Marvel...
A. Seth Grahame-Smith is a **** screenplay author. If you've seen his two previous fims (Abraham Lincoln: Vampire Hunter and Dark Shadows), you may be inclined to agree. So, if he really butchers this script, Fox may see fit to have yet another script writer try to doctor it up...and we all know that too many cooks in the kitchen can spoil the meal. In the end, Fox may really hate the finished script and feel the need to start over, which would buy us some time.
B. Fox is considering using the Skrulls and the Kree in this film?! Don't those properties still lie with Marvel Studios? If they do, Fox may be crossing certain lines in their contract with Marvel, which could give Marvel Studios some leverage in forcing the rights back due to a voided contract!
Now, obviously, these are pretty big stretches and I'm really reaching here...but I wouldn't say either of these scenarios are completely out of the realm of possibility.
KEEP THE HOPE ALIVE!!!
