With the way the Defenders ended for Matt/Daredevil the word is that season 3 of his solo series will be loosely based on the Born Again story line.
Speaking with THR, Charlie Cox seemed to confirm season three will be the show’s loose interpretation of the Born Again storyline, following where Matt ended up at the end of Defenders.
That’s such an amazing story. Everyone who loves Daredevil loves Born Again. You can’t not. And if that’s the case, then the implications of that would be very exciting to me. That would be great. Having said that, I know we don’t tend to follow any story blueprints too closely, because if you do, then you become a foregone conclusion.
There may be elements from Born Again, but I’m sure there will be elements that are unfamiliar and surprising and different in order for the show to be compelling to fans who know the comics very well. If we start making Born Again page-for-page, then the people who have read it and loved it  the hardcore fans  they won’t have too much drama.
