The premiere hasn’t even broadcast yet, but Disney has renewed it for the second season we all knew was in production anyway.
The show’s debut movie, ‘Spark of Rebellion’ airs tomorrow on the Disney Channel.
UPDATE: Greg Weisman has indeed left the show, as was first reported back during SDCC.
Official confirmation that Greg Weisman is sadly no longer part of the show. Henry Gilroy seems to have taken his place:
“The creative team behind the second season of “Star Wars Rebels” includes executive producers Simon Kinberg and Dave Filoni, and co-executive producer and supervising writer Henry Gilroy.”
