The now, presumably permanently, on hold live-action show, as well as the also on hold 1313 video game, would have dealt with the Dark Times period. In addition, it has been mentioned that the Clone Wars, if we see any more episodes post Season 5, would have gone up to and into the events of Episode III. Given the success of the Clone Wars series I wouldn't have been surprised, given it's popularity, to see a spin off into this era, or at least an adaptation of the live action show into this kind of an animated format given the estimated cost of doing the live-action show as, well, live action. All of this, of course, was fair game prior to the Disney announcement. Where such projects are, or may be in the future, at currently is anyone's guess outside of those directly involved with Lucasfilm and Disney.
