There's going to be a stronger X-Men push, while no one is saying anything about the Fantastic Four like they didn't say anything before either despite them actually leaving comics for a while, the the past 6 years of X-Men. How will this affect the Marvel Universe namely the Avengers?
We've already seen a shift of downplaying Avengers, the Fantastic Four, and inhumans in Uncanny Avengers. Emma Frost being forced into a marriage with a non X-Men book character isn't anything new since we had Havok/Wasp, Kitty/Starlord, Storm/Black Panther etc., but this is opening a door. And Fall of X is being used to push X-Men into other books more by gettin rid of their isolationist with monarchy status.
