The original plan was to plan out 60 episodes of TV, four 13-episode seasons for individual character setups and another 8 episodes for a team-up miniseries.
Going forward, Loeb and the Marvel TV division want to keep expanding their offerings on Netflix and everywhere else.
A few weeks later it became official that Netflix was to be home of the Defenders universe that would begin with Daredevil in 2015.
The notion of having all 13 episodes at one time, particularly in serialized storytelling, is very appealing.
