Yeah, it's going to be ironic. And yes, Episode IV will stick out but at least it gets the storyline somewhat back on track when Episode V arrives.
It is going to be interesting with the new generation of kids. I will tell my kids (when me and the wife have them) about the history of Star Wars but I'm not going to lie to you...I'm going to show them in numerical order first just to see how they respond to it. I mean, that's when we'll really know if Lucas is right.
I'm a Lucas guy who also realizes that he talks out the side of his mouth ever now and again. But, instead of saying the Saga is about Anakin, I wish he would've just stated that the Saga is about "the Skywalker family." With that, I think people would be okay with it. And what's funny about that is that Rick McCallum sees it that way and Lucas really doesn't.
