It is only a rumor, though one that seems to be gathering interest, and thought it worth mentioning on here…
‘RUMOR: animated sequel series to “Star Wars: Rebels” arriving this year?’:
Form the linked article above:
'Kessel Run Transmissions has released an exclusive via YouTube going into how the next major animated Star Wars series after the return of The Clone Wars will be a true follow-up to Rebels, continuing the story left off by the finale (in which Sabine Wren traveled alongside Ahsoka Tano in search of Ezra Bridger years after he helped oust the Empire from Lothal for good). This plot point has not been brought up at all since Rebels has ended, leaving the story an open door for whomever wants to tell the story… And that story may indeed be overseen by Dave Filoni, the showrunner of both The Clone Wars and Rebels.
The hosts of the Kessel Run Transmissions claim that they have received several major scoops that they did not run previously, but proved to be accurate, so they felt confident enough to run this story – especially in light of some new, currently-unspecified evidence that they’ve received. They claim that two reliable sources are telling them that the Rebels sequel is moving forward:’
“So what we’ve heard is that the Star Wars Rebels sequel show is in development, it is gonna be animated, it is set for 2020 – this year – yeah, and so that’s pretty exciting. That’s almost a given, too… In a development process, that’s natural for it to come now – Resistance is winding down this year.
The show will star Ahsoka and Sabine – again, another given, but we’ve got confirmation of that – and we’ve heard throughout the months that Dave Filoni is also attached to an animated series. We’re assuming it’s this one… It’s a good to bring that show back. Obviously, it’s not going to be called Star Wars Rebels, we have no idea what it’s gonna be called… I’m excited because this continues the story of Ahsoka, and we’ll get to see what she’s doing.
We haven’t heard about Ezra and Thrawn, but I’m assuming that they’d be in this series… I did hear that the animation is supposed to be a lot tighter than it was for Rebels [in its] four-season run… They’re probably into Season 2 by this point.”

I hope this is true - a new animated series, a little more adult orientated than the ending Resistance series would be most welcome, and fill a lot for the new Disney+ streaming service. I hope we see new characters introduced, maybe just a few characters from Rebels into this, and in new settings too?
It is just a rumor - but wouldn’t be surprising if a new animated series was announced soon?
