He wants EVERYONE to see the saga 1-6, he wants EVERYONE to recognize the PT, the SE, and not the OOT. He wants everyone to see it as the story of Tragedy of Anakin Skywalker, that is why he has Hayden there now instead of Shaw at the end of ROTJ. He doesn't want to put out multiple versions everytime on DVD, he would rather just put out 6 movies of the version he feels is the story he is telling now.

Here is the problem with that, a majority of SW fans don't see it that way, and he has a dilemma now. He did the same thing to SW'77 fans back in 1977, either see the story as the OT, or don't, as he changed SW to Episode IV: A New Hope. Alot of fans are still just SW'77 fans, but a large chunk of us loved ESB, like ROTJ and went with his vision of seeing the story not as originally intended, but as Darth Vader, Luke, and Leia all being related.
What will eventually happen is Lucas will realize that a huge part of the fanbase will just not recognize the SE/PT as canon, and although there is many of us that will put up with the SE on DVD, cause they are great quality DVD's, we still prefer the OOT instead. The DVD format for SW has been screwed up since day one, as the OT/SE took 7 years, TPM took 2 1/2 years, and only AOTC & ROTS came out day and date. And finally the OOT came out in halfass quality in 2006 to finally put the nail in the coffin that split the fanbase up.
HD-DVD/BlueRay will correct all this nonsense, cause the Saga is done now, the movies are done, and Lucas doesn't have anything new. Just the fact that the OOT came out on DVD, albeit crappy DVD, shows that Lucas knows there is a market for those movies, as Lucas said in 2005, "People under 25 love the PT, and those over 25 mostly have not liked those movies." I am paraphrasing and it is a general statement cause not every over/under 25 feels that way, but that statement tells me Lucas knows what the fanbase wants, and he was just trying to get fans to see it the way he wanted to. Unfortunately to alot of diehard SW fans, he failed with the PT/SE, and he knows there is a huge OOT fanbase out there who will still buy anything from 77-83. Wait for HD-DVD or BlueRay, that will finally give us what we want, cause SW is a bigtent fanbase now, it isn't just SW'77, or the OT, or the saga, as Lucas has tried to get his fanbase to evolve to over the years, it is all 3.
