Yeah, I wish there was some way we could see definitive numbers on how the GOUT's sales stack up against the 04 set's, though I really don't think there were that many people who didn't buy it because they knew it was non-anamorphic. Most people probably think all standard dvd's are 4:3 letterbox (how many times have we gone over to a friend's house and needed to set their dvd player to 16:9 because the picture was all stretched out?), so the people who didn't buy it either a) aren't star wars fans or b) already had the '04 set and don't care about the alterations. But there's obviously a large number of people who are neither because the GOUT still sold quite well. Even the knowledgeable on this very forum were saying they bought it hand over fist because it might be the best we ever get.
When the blu-ray comes out, there won't be some way of fooling everyone who doesn't know any better. There is only 16:9, so that's what the OOT will have to be if they include it. Of course, I'm sure they could pull something just as annoying and include a 16:9 480p mpeg-2 transfer in the corner of the same disc that has the nice 1080p SE, just so they wouldn't have to put the original version on its own disc.
Here's what I'm thinking: it only took six years for dvd to overtake vhs, which is why Lucas released the OT in '04 instead of waiting even longer like he'd originally planned. The live-action show is hitting circa 2012, and I'm betting Lucas will put out the blu-ray right before then. Live-action tv is the only medium Star Wars has never been told in, barring the holiday special. Call me naive, but I would think they'd want to make the blu-ray the definitive set at least so far as non-downloadable content goes (bd-live will allow them to put out more extras later). Once the show is on the air, I would think it'll be all about the show and - later on - the blu-ray and dvd season sets. Blu-ray will be big by 2012, but I'm thinking it's not going to be so big as dvd was in '03 (six years into its life). Maybe zombie's dire prediction of "star wars on blu-ray" being enough of a selling piont will come true, but people only had nine years with dvd before a new format came out. They're not going to be in a rush to buy Star Wars again unless it has what a lot of them want.
