Lucasfilm has a historical pattern of screw ups when it comes to Star Wars on DVD. First TPM has bad colouring and EE to the extreme in 2001, then OTSE is a total and utter fail in 2004, then the OOT is a total and utter fail in 2006. Instead of fixing them, they re-release the OT in at least three additional re-packages with all the same problems--surely if Lucas was aware of the issues he would fix them, if the films are not supposed to look like that. But with him supervising and approving the transfers himself, and watching said transfers himself on a number of occassions, he seems to deem them fine.

They've been airing the HD OT masters for years now. Also, while the SW in Concert tour had the new TPM footage, the OT footage appeared to be the same as the 2004 DVD. Plus, the trailer for the release promoted the films using new TPM footage and the same OT footage from 2004. Also, was it Steve Sansweet who said that the HD masters have been ready for years now?

We will wait and see, as you said. But there is ample reason to doubt Lucasfilm corrected anything, and based on their past history I think optimism is a bit naive. I will add that to me there is some possibility that they may have corrected some of the lightsaber issues, but this is total speculation on my part. It would be nice if they fixed all the issues, I guess, but history is not on Lucasfilm's side.
