I'm a bit confused. The studio isn't working on new episodes, but it is working on new stories. For what? TV specials? Un-aired, but already created episodes that need final touches?
And that clip at the end of the linked video is interesting. Was that one clone the guinea pig for order 66 or was he a "glitch" that lead to the idea of order 66? The theatrical movie had dialog that stated the clones were genetically engineered to follow orders without question. This clone acted more like he was under hypnotic control or something like that rather than blindly following orders.
As for what happens to Ahsoka - unless there is something already out there from Lucasfilm, in my little world she hooked up with Asajj and the duo became one kick-*** bounty hunter team.
