Empire Magazine provided us with word on what Daredevil director Mark Steven Johnson is saying about the Elektra spin-off and the sequel.
...both projects are definite, with Elektra coming out first, and believes in Elektra (on which he is producing, not directing) succeeding as a movie in its own right. The movie will be set after the events in Daredevil. When asked if Daredevil himself would make an appearance, he replied: "It would be nice if we saw Matt [Murdock] at the end."
On Daredevil 2, he says they're still playing with ideas, but believes the natural thing would be to do movie versions of either the classic Guardian Devil or Born Again storylines.
