At tonight’s Luke Cage panel at San Diego Comic Con, Joe Quesada came out to announce that Daredevil had been picked up for season 3 on Netflix. Marvel also dropped the following teaser on their Twitter page using the subway lines as nods to the 3 seasons Daredevil has now received.

No release date has been given, but the likelihood is we should see season 3 release in a similar period to seasons one and two sometime in 2018. It is unlikely for season 3 to drop next year as Iron Fist and The Defenders need to be released first.
