You are right @Trebor Sabreon we should be getting this kind of info from Filoni himself. The frustration is that those who get to interview him either skip over these sorts of questions or are told not to ask them due to the focus on Rebels. In fact, for the WonderCon Rebels panel, they let folks submit questions in the comments section of a Starwars.com blog post. I looked at all of them and about 75% were asking about Clone Wars untold stories. Not a single one was asked, all the questions that were picked were related to Rebels, so they are controlling the message. Dave is always cool about answering stuff and engaging the fans, but it looks like Lucasfilm is putting up embargos. I think it would be good to keep pushing these through when possible, it wouldn't be in their best interest to ignore it if there is enough interest there. Oh, and to your other question, it wasn't announced yet officially that there will be a SDCC panel for Star Wars, but it's widely believed that Rebels will have a presence there. Filoni has come out for that often when it came to Clone Wars, and since he made it out for Celebration and WonderCon, it's likely he'll be there. But they may control all discussion to be Rebels related.
