To date, only two spinoffs (Rogue One: A Star Wars Story and Han Solo) have been officially announced.
Their source says that “there is a real sense of excitement around the Han Solo movie and its potential.”
Rogue One: A Star Wars Story opens in U.S. theaters on December 16, 2016, followed by Star Wars: Episode VIII on December 15, 2017, the Han Solo Star Wars Anthology film on May 25, 2018, Star Wars: Episode IXin 2019, and the third Star Wars Anthology film in 2020.
Han Solo is one of the most beloved characters Lucasfilm has at their disposal, so if Ehrenreich’s version is well-received, they would obviously be interested in making more films with him.
