[[wysiwyg_imageupload:8936:]]Add a third as-of-yet unknown movie to the Marvel Studios slate as a July 16, 2016 release date has been announced.
Just last week, Marvel Studios and Disney announced May 2016 and 2017 release dates for unnamed movies as well.
More than likely one of the dates mentioned above is for The Avengers 3 (probably in May) as it was just officially announced that Robert Downey Jr. will be returning for that and The Avengers 2.
However, the announcement made no mention of an "Iron Man 4," so one of the May dates above looks to be launching another big Marvel Studios property.
Both Iron Man and The Avengers had May release dates.
As it stands, Thor 2 is next inline on November 8th, which is followed by:
Captain America 2 on April 4, 2014
Guardians of the Galaxy on August 1, 2014
Big Hero 6 (animated) on November 7, 2014
The Avengers 2 on May 1, 2015
Ant-Man on November 6, 2015
Unnamed Movie on May 6, 2016
Unnamed Movie on July 16, 2016
Unnamed Movie on May 5, 2017
There's been mention of possible Doctor Strange, Inhumans, Heroes For Hire, and Black Panther movies.
