I believe Filoni's continued involvement was confirmed by a Disney executive during a conference call. They would be foolish to get rid of him.
I'm disappointed about the rest of the team being let go or re-assigned but not surprised. I expect Disney will do away with LFL Animation. It's what they do, they have a ton of animation studios and I don't see them keep a distant foreign one around. It's a shame...Clone Wars blew away just about every Disney television product out there.
I don't think Disney hates The Clone Wars. More like they simply don't give a fuck about the show or its fans. I hope I'm wrong but I wouldn't be suprised if we don't see any of this "bonus content." When you don't give a fuck about something, you're not exactly in a rush to do more of it. I find moves like caneling The Clone Wars by Disney and others to be unnecessarily hostile towards the fanbase.
It's a shame too because a character like Ahsoka is unlikely to ever appear again onscreen, at least not for a long time.
This might have been the original report...
