Aaaaaaand it looks like Marvel's getting back the Daredevil rights:
Remember that "Let us use Galactus and you can keep Daredevil for a while longer" trade Marvel offered to Fox a little while back? Fox passed, meaning the Daredevil movie rights will revert to Marvel some time in October, and director Joe Carnahan's vision of a gritty, Frank Miller-before-he-totally-lost-his-mind-esque set-in-the-'70s Daredevil movie is basically dead.
If this is true and I'm understanding it correctly, it means that all the following characters:
Daredevil/Matt Murdock, Elektra (Natchios), The Kingpin/Wilson Fisk, Bullseye, Jack Murdock, Karen Page, Ben Urich
can now appear in official Marvel films and can, theoretically, show up in a future Avengers film.
