Season 3 has been confirmed at SDCC! There is a teaser at the link, but it's not on YouTube yet that I could find. The Defenders teaser seemed to indicate that that show would be picking up season two's hanging Hand threads, leaving many possibilities open for season three. There is always the possible return of Wilson Fisk. "Born Again" would indeed be a great story to adapt. They've already cast Nuke, so... Hopefully we'll get an MCU Bullseye, and they keep building up Melvin Potter, so perhaps some Gladiator action?.
