I tried to view the RotJ footage with the prequelesque lightsaber sound but it was gone. I did check out a similar video of part of Empire's fight with new lightsaber sound FX and I REALLY, REALLY like the idea. Makes the lightsabers sound more powerful and I am all for that. Adywan you should check that out.

Definitely add the scar.

and last but not least no more additional ghosts. Luke doesnt know them. And I think a Hayden blend into Shaw ghost for the the rest of it. But thats just me.
