I don't think it will, personally. That's what I dislike about Marvel pushing the couple everywhere. I like them as a couple, love the way they were depicted as a pairing in Whedon's Astonishing X-men (and by extension, Ellis') but Marvel have done a pretty good job of taking a nice couple and pushing them so hard they start to lose some of the appeal. Like they couldn't just be a nice coupling which last as long as they last, they had to be centre of the entire Marvel universe or something. It means if/when they do split it's going to be so damn overblown.
