I know some of the concepts George threw around for his versions of 7, 8, and 9 were to explore the "microscopic" aspects of the Force, so more stupid midichlorians etc. Perhaps the new villain would have been disease and watching a person lay in a sickbay fighting off said disease for 3 films. Yawn.

No thanks George. I'll pass.
I wouldn't have liked his concept any better than what we got, nor has my distaste for the ST made my perspective on the PT change, because I still hate those movies too. They suck. So I am far from the type to start lamenting George's departure entirely. Though I don't outright hate him either and my hope is that he still has some talent left in him. Though we will never know now because he's hellbent on hiding his current films from the world.
What I am interested to see (though I suspect that Lucasfilm under Kennedy would do their damnedest to hide it) is what the truth behind these new films really is? It's certainly more volatile that they make it out to be and though the public may never know the whole truth, I think there is a level of duplicity to it all that makes my stomach turn.
I think Hubris has always been a central theme of the Empire's downfall and why the Rebels managed to eventually defeat the Empire (at least in the three original films) though it was never stated outright.
Their arrogance often led to their defeat at many points in the story.
So basically Hubris is not a new concept in the Star Wars films, only now the focus of that Hubris has been shifted to the heroes and not the villains. Which I personally hate but to each their own.
But back on topic.
The initial article really doesn't come as a surprise to most Star Wars fans that have been paying attention. Perhaps this is news to the general public, but for Star Wars fans, no matter how you feel about the new films, this was never hidden if you watched closely enough.
