Matt Fraction talked to John Siuntres on Word Balloon a couple of days ago about Fear Itself. So what do we know?
Well, the series will centre on Thor and Captain America, an Eden-like myth in Norse history revolving around the God Of Fear, the serpent cast out by Odin, killed his followers and churches and has hidden his existence. And Sin, the daughter of Red Skull, and now the new Red Skull, finds him.
A god that thrives on fear itself. And the more you fear him, the stronger he becomes, and he launches a war on earth, scaring everyone and turning each person into a weapon feeding Fear.
It's designed to be modular. Like Civil War, you can just read the series and that's fine, but you can spin off on tangents in other books if you wish.
For speculators, if you want, Sin's first appearance was in Captain America #290 as Mother Superior. In issue #355 she is known as just Sin, one of the Sisters Of Sin, and was recently revived in Ed Brubaker's Captain America#16, becoming facially scarred and the new Red Skull is Captain America Reborn #6. And she's just been broken out of jail… so hit those back issue bins…
