Kevin Feige was interviewed by Wired this is what he said.
“Five years ago, looking at our plan, we knew that if Avengers was going to work, the movies had to stand alone. Now we have to prove to the studio that we’re more than just these five characters, these five franchises.” He carry's on to say. “I could arguably say what we’re planning for the year 2021,Will that happen? I don’t know. But what we planned for 2015 in 2006 is happening".
so far there are two unspecified movies to be released in 2016 and one in 2017. Let us know what you think they could be or what you would like to see. The rumours so far suggest Doctor strange and Black panther films.
