I'm sure George would have pushed forward with the SEs anyway. He had to do something for his test dummies for the prequels. Grr, am I the only person who gets offended when I am reminded of that? But, anyway, to not derail my own post... Knowing George (which I don't, personally), I wouldn't be surprised if he got so bitter that his SEs didn't sell well, that he would have obliterated the OOT anyway, just so we'd have to watch it. So, really, not much different from our current reality.
