Amazing that supershadow is still around. His site used to have a disclaimer that it was all "made up for fun" because Lucasfilm finally went after him. But I don't see the disclaimer up there now.
I read today that Lucas was auditioning writers and plotlines during that July to August development period for ep. 7. So he wasn't even going off his old treatments. He had no clue what ep. 7 was going to be or should be.
For some reason that makes me feel abit better, the idea of him stashing the plots for 30 years and lying about their existence really sucked.
