I wouldn't be surprised either. If the Blu is indeed the 2004, at the very least it should be color corrected to look more like the actual film (at least restored to the 97 look like Adywan's ANH and ESB.) and have all the nagging visual and audio problems fixed. (Why the heck didn't they just clean up the 97SE version-at least that is watchable!)
This shows that Lucasfilm is behind the format. It would make sense for them to finally end all ill will and negative feedback from fans by releasing a comprehensive Blade Runner style set but I doubt it will happen. Dream of it, yes-but think it will really happen, no.
A Star Wars Blu-Ray should include restored theatrical originals with as many soundtracks as are available and the 1997 Special Editions with the 1997 5.1 mix. Any other final cut can be an extra. Deleted Scenes should finally be included as well as alternate takes etc. It's not like we haven't waited since the birth of home video for a truly "definitive collection".
I won't buy the thing if it is just the 2004's all over again. I still remember the gut punch the night of September 21st 2004.
