I still don't see them going back to PT-era anytime soon, unless somehow Episodes VIII and IX tie into that trilogy more than expected and help redeem them in the public's eye. Besides, they seem to wanna center these spinoffs around characters or events we're already familiar with, there isn't a whole lot of ground DURING the actual PT left to cover thanks to the Clone Wars show (they could always cover ground between Eps. I and II, but since those are the two least-popular movies in the franchise it just doesn't make a lot of sense).
