I'm sorry but there to much proof aganist it, theres clips of Mark Hamill saying:
'At one point George Said: How would you fell about playing an Obi-Wan type character and pass down the lightsaber to another Generation. And I said well, when would that be and he'd say about 2010! And I would think it would be great to have something around the turn of the melinia!'
Or something along those lines. Lucas wanted to do 9, why else write a treatment for it? And he claims to have not read the novels? then anything could happen! People could make Han ditch Leia and go gay and want Luke! Would Lucas want that? NO! He'd have t stop it but how when he doesnt read the novels?
Lucas Lies: FACT!
