I did pre-order the Blu-ray set, but after seeing some of the new changes I changed my mind and cancelled it. The only thing left on this set that interests me would be the bonus features (and the fixed German audio), but that's not worth 90 bucks to me.
As my nick and avatar show, I am a Star Wars nut... since forever... but as much as I would love to have the films on Blu-ray, the ways the films are now they simply aren't any fun anymore for me. Some of the changes make me cringe, and now some make me really question the sanity of GL.
If you're really against the way he treats the classic trilogy right now, go ahead and write a negative review at Amazon.com
... explain why you won't buy. It's already down to a 2.5 stars rating and it's possibly one of the few ways to let Lucasfilm know, what you think of this.
