Or, more appropriately, will the blu-ray set really be worth buying solely for the movies?

Let me explain. Here are a couple of screen captures from Wookiegroomer's RoTJ (DVD9 version). I believe this release was created from the German HD broadcast, but I could be wrong.

Very high quality stuff, I'm sure you'll agree. Aside from the obvious benefits of a much larger storage medium, can we really expect a huge quality increase next year when the blu-ray is released? Will Lucasfilm even bother with new scans of the OT, or will they stick to the 1080p HDTV master that Lucas and co. seem quite happy with?

Audio too. Do you think they will go back and fix the godawful soundtrack of the DVD release?
