There had been rumors that George Lucas was developing a third trilogy for several years, but when George Lucas sold his empire, he relinquished all control to Disney, and he was not involved in any way in Star Wars: The Force Awakens, or its upcoming sequels and spinoffs.
Disney discarded his ideas, telling the filmmaker they wanted to make something for the fans, which George Lucas called a “retro movie,” in his interview with Charlie Rose before Star Wars: The Force Awakens was released.
There is speculation that young characters such as Kira, an early version of Rey (Daisy Ridley) and Sam, who were featured in concept art from the book The Art of Star Wars: The Force Awakens, could hint that these characters are who George Lucas wanted to build his trilogy around, although that hasn’t been confirmed.
