I believe that's what the fans of The Clone Wars want, to wrap up the loose ends left by the show. We know it couldn't go on forever as it was already nearing ROTS. Lucas and Filoni had 2 more seasons planned to finish wrapping all the loose ends and transitioning the show into Episode III, which included the events of ROTS though the point of view of The Clone Wars characters. Brent Friedman a writer on the show has said they had finished writing the episodes up to the series finale. I love all Star Wars, I don't have a favorite movie or era, to me it's just one big story arc all connected. I'm looking forward to all the new movies and shows, but it really saddens me that they have left this gap in the overall story arc of the Star Wars Universe and saddens me even more when I hear people don't even care about these stories which are Lucas' own final stories in Star Wars.
