Bill Hunt of the website The Digital Bits also had the opportunity to preview the upcoming Blu-Ray editions of complete Star Wars saga. One note that Bill made, that I am particularly jazzed about:

"Some of you may recall that on the 2004 DVD, when the X-Wings begin their dive down to the Death Star, the familiar John Williams trumpet fanfare was buried in the mix so you could barely hear it. No longer! The trumpets ring true in the Blu-ray mix loud and clear."

It seems clear that a lot of effort is being put into this release to fix many issues that fans had with the previous DVD releases. Check out the rest of Bill Hunt's thoughts on his preview experience here: http://www.thedigitalbits.com/articles/starwarsbds/preview.html
