"Daredevil" will be reverting back to Marvel in October. That's pretty much established. Joe Carnahan's pitch was Fox's last ditch effort to find someone.
I'm sure CorporalCaptain is referring to the popular fan theory that Coulson will be resurrected as the Vision rumours that have surfaced since the "Avengers", unless there are new rumours that I'm not aware of regarding how Coulson could return. Revealing that Coulson is alive would defeat the purpose of his death being the catalyst for uniting the team. Joss would not have done that. Coulson's death kind of reminded me of Wash's from "Serenity".
