Once again, Marvel has no hope of getting Spider-Man or X-Men back any time soon. They won't possibly be able to pay the amount of money it would take to buy the rights back, and so long as FOX continues to make Spidey and X-Men movies, they'll be able to hold onto the rights.
We actually have hope for Fantastic Four though, as FOX doesn't seem to care about those rights anymore, so Marvel might at least get them back.
