The X-Men relaunch is already getting retooled.
The creative teams for X-Men Gold and Blue will be changed out after the first arc (roughly around issue #5). Kyle and Yost has been approached to write the books, with the sales gimmick being that the stories will continue between each book, forcing fans to buy both books to get the full story being told. Furthermore a third as of yet untitled core X-Book is going to be launched: focusing on the adult versions of Beast, Iceman, Archangel and Madelyne Pryor, as they team up to bring adult Scott Summers back to life and deal with the fall-out from Secret Empire/Hydra Wars.
Iceman and Jean Grey are not officially stealth mini-series and the covers/promotion will reflect this, as Marvel feels that pushing them as mini-series might sell them better to comic shops/allow them to save face.
Marvel's going to cull the bulk of their line following Secret Empire/Hydra War. There is talk about major character deaths to explain away cancelations. No one is safe, not even Miles Morales.
Preliminary death list for Hydra War/Secret Empire: Hellcat, Miles Morales, Mockingbird, Jane Foster Thor, Amadeus Cho, Falcon II, Mantis, Nova II, Monica Rambaeu, Quicksilver, Steve Rogers, Silk, Kate Bishop, the Thunderbolts, the Mercs for Money (Domino, Slapstick, Solo, Stingray, Terror, Massacre, Foolkiller), Rogue, Moon Girl, Ms America, the US Avengers, and possibly several of the newly created Inhuman characters.
Steve Rogers will die in Hydra War, leading to Marvel launching a trio of Cap spin-offs to try and pander to fans of all stripes while they figure out who will be the permanent new Cap:
A. Falcon Cap, which will deal with social justice matters
B. USAgent Cap, which will be more conservative leaning/traditional super-hero stuff
C. Bucky Cap, which will be more or less "Cap travels America" stuff
