I can't see him spending any more cash than necessary on the OT for a HD release. they're already available in 1080p HD and to fix the problems he would have to rescan the negative, do the restoration work and colour correction all over again.

I've read that even though a lot of transfers for dvd have been done in high definition, they've had to redo them for the blu-ray releases because HD scan from 2004 is good enough for tv but not home video.

Of course that doesn't mean Lucas will have the films rescanned, it would just mean he would be extremely lazy to do so (which he already is). But he'll probably change even more which hopefully won't sell well and make even more people demand the originals.
