Well about 100 episodes was what they planned and they've passed that with more to come. What we get next will wrap up the series which seems good to me. I don't think they could fit that many more adventures into a 3 year gap and season 5 wasn't the best, it seemed to be milkin it a bit too much.
I hope they do the live action set between the prequel and original. I think anything set after the original trilogy would get in the way of 7,8,9. Then again the live action series might get in the way of the standalone movies.
Too much star wars is the problem now.
