I think the flash/glow as the sabers are in contact with each other is a PT addition to the sabers that they actually got right and improved them. But all the other changes to the sabers like removing the flickering, giving them pointed ends & making them too sharp ruined the PT sabers.

Plus, the PT lightsabers no longer have that crackling sound when they clash!

Also, for the ESB:R blu-ray, will you be using the new 6.1 DTS-HD MA track as a basis for it?

Provided it no longer suffers from swapped channels/muted audio like the DVDs. I really hope that this will be the best Star Wars track ever, apart from a few audio changes like restoring Boba Fett's original voice :)
