There is already a new date for the premiere of Guardians of the Galaxy 2 and it has been advanced to May 5, 2017. This change has been made to be able to adapt well to the arrival of many films that were going to be released on dates close to the one they had originally planned and thus not lose screen share.
Although there is still a long time to do so, other films have already been announced, such as The Avengers 2, which will be released on May 5, 2017. On July 17, 2015, Ant Man will finally be released. Captain America 6: Civil War will be released on May 2016, 3 and Doctor Strange will be released on November 4 of the same year.
Continuing with this movie release schedule, Thor 28 Ragnarok will be released on July 2017, 3 and then it will be Black Panther's turn, which will be released on November 3, 2017.
Avengers 3 also has a date, but there is still a lot of time, it will be in the month of May 2018, on July 6 of that same year Miss Marvel will come out and finally, November 2018 is the date chosen for the premiere of Inhumans.
