According to Deadline, Disney and Lucasfilm could be developing a Boba Fett series for Disney+ — and it could start filming soon, depending on which sources you listen to.
Whether that means the main series or a potential spinoff series set in The Mandalorian timeline remains to be seen.
However, some sources are suggesting the next season will be pushed to spring 2021 to make way for the aforementioned Boba Fett series, which would begin filming next week.
Lucasfilm is keeping details about either project a secret, though it was recently announced that Sophie Thatcher would join The Mandalorian franchise in an unspecified role.
