Semi-related news.
Star Wars: Resistance will be the next animated Star Wars series to come out this fall.
Also Forces of Destiny came out with another set of seven short episodes for May the Fourth (on Disney's YouTube channel), which includes some stories related to Rebels...but also the old Ewoks cartoon, Return of the Jedi, The Force, Awakens, The Last Jedi, and the Phantom Menace (well sometime after that, but before Attack of the Clones...while Padme is still Queen of Naboo).
