The reason I say this is if you watch the Jon Stewart interview with Lucas last month, Lucas made a point of saying there are 2 SW fanbases, the OT fans and the PT fans, so he is aware that many fans prefer one trilogy over the other.

Yeah that was interesting. We know LFL market-researches the shit out of everything, he's probably looking at data we aren't privy to. That plus the Clone War kids who are all about the cartoon makes it a real mess if he insists on releasing it only as a definitive "tragedy of anakin saga box". The sales pitch essentially becomes: Hey everyone! Spend 180 bucks on this! You'll only hate some of it!
