Marvel has released an additional Joe Quesada-illustrated teaser the upcoming 50th Anniversary of the Fantastic Four in November, which not only seems to indicate that Fantastic Four will return for #600, but it also seems to tease that Johnny Storm will be returning – a fact that very comic fan who has seen these kind of things happen before has assumed will happen since he died.
The rumor is, as started by Bleeding Cool (I assume, anyway), that Fantastic Four and FF will both exist in the same place, with – supposedly – Valerie finally launching her assault on the N-Zone against Annihilus, where they will assumedly find Johnny chained up and being abused somewhere.
I guess we’ll find out in November.
