Marvel released a pair of teasers with one for the upcoming new Inhumans event and another about "Resurrection" from Brian Wood and Kris Anka.
The speculation online for quite a while regards to the new Inhumans event is that Marvel Comics and Marvel Studios are going to be using the Inhumans basically as a replacement for the X-Men and mutants, as Disney doesn't own the movie rights to X-Men. As a result of the events in the Infinity event, Black Bolt unleashed a terrigen mist bomb that activated dormant Inhuman powers on the people of Earth, in effect giving them all different powers and creating outcasts. Sound familiar? Sounds like Fraction, Brevoort and Alonso have an uphill battle on their hands with this one.
The Wood teaser could be something X-Men related as well, or who knows maybe Adam Warlock.
