Re: MCU: Phase II - Part 1
^ Inhumans is definitely happening, so it's three.
Also, if Marvel can't produce more than two right now after Avengers, why would they suddenly be able to produce twice as many in less than 5 years? It's not like they don't have Disney backing them right now.
Also, I don't like using the term saturation, but they'd be dangerously close to putting out too much with that kind of schedule.
