I bought the set. Yes, shame on me. Two weeks ago I was boycotting it, and I've been one of the most critical people for about a year. But I got it, I guess because it's Star Wars on Blu-ray. :P
I don't feel like giving LFL the money for these, but to be honest I watched ANH and I'm honestly very happy with what I got. I don't regret it at all. Maybe but it's because I've never seen the HDTV broadcasts before, but the PQ was very sharp to me and the black crush was better than on the DVD. Granted, it looked like they'd just brightened up the picture at times. For example, during the escape from the Death Star one of the TIE Fighter pilot's helmet is completely in shadow, but it's actually a flat grey. Audio quality was outstanding. Overall I was really surprised by how good it looked.
The worst (new) change of the Blu-ray for me actually was the rocks in front of R2, simply because it wasn't consistent at all.
Especially when I put my TV on warm, the colors seemed very accurate to the original film. I hate black crush and blue tint as much as anyone here, but there was no blue tint in what I saw and the black crush was only noticeable in a few scenes. With my TV settings the Death Star actually looked grey-green.
For TESB...I've got my own TV calibrations to completely remove the blue tint on Hoth and shift Vader's saber from magneta towards red.
I'm not sure what anyone's talking about when they saw the matte boxes are gone. They're more obvious than ever.
The deleted scenes are pretty bad. For anyone interested in recompositing it the original opening space matte painting is featured in HD.
After watching the Blu-rays I'm going to watch Harmy's despecialized versions. I honestly think that if Star Wars in 3D fails we'll get the OOT on Blu-ray in the next few years.
