Well I was actually there at Celebration

I was able to catch a good chunk of ANH. First of all, the quality of the footage was amazing. Brilliant definition. It was projected onto a huge digital screen and it was just breathtaking.

I think what they were playing is what's going to be released on bluray. It seems like they fixed some of the errors the DVD release introduced as Luke's saber was actually white during his remote training and the color overall looked a LOT better than what I remember from the last release.

I think there is still hope for a decent blu-ray release. May not be the OOT but at least hopefully a better transfer of the SE.
