I could see it going either way.
I don't know. I could almost see them (and the marriage) erased from history somehow. I think when the Fantastic Four eventually do return, it won't be the same. Some part of the dynamic will probably be changed just so Marvel can get some extra attention for it. That's why I think they're better off leaving the FF in the 20th century, or on some alternate earth, and having them kind of become Marvel's answer to The Justice Society. Marvel is so screwed up these days that they're bound to screw up the FF.
