So, I can't necessarily state my sources other than saying that it is from a reputable source within disney. But, I happen to know the attitude at disney towards all things prequel and special edition is very negative and have heard that restoring the original, unaltered trilogy is a priority on the Star Wars front, though their focus is mainly on TFA, the spinoff films, and rebels at the moment and it is unclear when we will see a release, but that it is going to happen within the next couple of years.
