I’ve been the “expert” several times (on here too; I’m sure you remember, Frink 😉), but in the times coming to my head now, I honestly thought I was remembering my facts correctly (or I stated my being unsure). But I do have a little story to add:
One of my older brothers told me that someone he was talking to said something to the effect of “George Lucas already has the scripts for episodes 7 8 and 9 written.” This was back in like, 2007.
While “already having the scripts” is probably a little too far it seems like he did indeed have enough story for 9 or 12 movies to begin with. But more likely as notes, ideas and outlines and such, than actual scripts.
