They pushed everything back for a second season of Daredevil. I could see them pushing the Defenders back for a season of The Punisher.
The Defenders is in a weird spot. It has to come out next year if they have any shot in being in Infinity wars.
But do we really see Netflix releasing 3 shows in a year??
(Then again 2017 is the year Marvel starts releasing 3 movies a year)
If i recall correctly the defenders is a "Miniseries" and not a full fledged 13 episode series. So they could release it end of year if it's only 6-7 episodes. This also makes sense cause they are filiming "The Defenders" and "Jessica Jones S2" back to back.
'Jessica Jones' S2 Filming Back-to-Back With 'The Defenders'
Regardless on when they come out im banking the netflix schedule is
Iron Fist
The Punisher
The Defenders
Jessica Jones Season 2
Daredevil Season 3
Misty Knight(i can hope)
