Disney decided to cut the entire series so they could divert their attention to making the new films, so we aren't seeing anything for a while - but it has been said to reguarly check the SW website as it may be released in small videos etc. Dark Lord 21 (talk) 14:02, April 13, 2013 (UTC)

In an interview with Kevin Kliner, he said that there are around 10 episodes that they are working on for the bonus content. This is likely in addition to the already completed arcs. He hinted at a DVD release and a possible Clone Wars soundtrack.
Here is a quote from the interview:
"We have about ten shows that we're still working on that are going to be part of the special material. And even, hopefully, there's going to be a soundtrack record as a part of this special material... They're in negotiations about that so we're not positive that's going to happen."
I have really been looking forward to that arc. I hope we see it. My theory is that Boba Fett kills Cad Bane at some point which earns him the his name as the most fearsome bounty hunter out there and all that.
