There's the oft-touted bit about always envisioning a 9-part saga. Conversely, Lucas didn't let audiences onto this until after the commercial success of SW (ANH). My dad remembers seeing the opening scroll for ESB, reading "Episode V" and thinking he'd missed four movies in between.
It's easy to be grandiose as a billionaire, that he had a 9-part epic. As a struggling director with no real collateral to your name, I think he took the most entertaining part and bet everything on it. If successful, great. If not, it was just a story.
