RUMORS : List of possible Blu-Ray visual changes:

Asteroid field garbage matte removal or deflector shields: http://d2np6futyd7kp6.cloudfront.net/images/600px/ep5/EP5_ILM_62.jpg

There's no garbage matte removal seen in that picture at all, the garbage mattes are in fact just more visible:

I just see a horribly destroyed image where the black levels have earlier been crushed and where someone has tried to bring back the lost detail in vain by boosting the gamma. The result is a completely lifeless, desaturated and unnatural ugly mess. This is most likely how many scenes will look on the blu-rays, but as long as it is presented in 1080p, people will buy it and be happy.

This is more how it should look:

Even the washed out and low-res THX-transfer/GOUT is quite beautiful when compared to that screen-cap. Don't let these people restore the original films the day it hopefully happens.
