Remember the last time Fred Van Lente was making splashes on Twitter? He was discussing news of his upcoming Avengers related project and speculation ran rampant about a Cosmic Avengers title. And back during Comic-Con, Andy Lanning asked the crowd if they were interested in a Cosmic Avengers title as well, which was met with lots of applause, though no announcement ever came of it.
Can't discuss post-CHAOS WAR plans for iHerc characters. Or the GP/FVL duo. But big things are in the works for at least one of them.
Seeing as Van Lente is currently writing a huge cosmic-level event with his own brand of Cosmic Avengers (Herc, Thor, Galactus, Silver Surfer, etc) and that there is definite overlap with the other cosmic titles, the possibility of a Cosmic Avengers being in the works seems more and more likely. Even Bendis is moving the Avengers towards more cosmic titles with his Hood/Infinity Gauntlet storyline coming up in the regular Avengers title.
