During a panel at the Sonic Revolution convention, the original Sonic Boom creative team have confirmed that they are no longer working on the show.
When asked whether a third season was happening, head-writer Bill Freiberger confirmed that he, along writers Sam Freiberger, Alan Denton and Greg Hahn all confirmed that they were in no longer working on the show, and so therefore could not comment on the future of the series.
While not a confirmation of the show’s cancellation, this can’t be good sign for the show’s future. According to Freiberger, only SEGA really knows the future of the show right now.
The panel is currently running on Sonic Revolution’s YouTube livestream. Unfortunately, the video appears to be out of focus, but you can still hear it!
UPDATE: Freiberger has clarified with us that, even though they are not currently involved with the show, this does not mean they will not be involved in a future season.
We were also able to ask Aaron Webber about the future of the series. He uncharacteristically said “No comment.”
