I'll add one more if you're talking about non-Star Wars preservations:
THX 1138. That's getting a brand-new laserdisc transfer thanks to SilverWook, though it's currently up in the air as to who is getting the raw AVI to make a DVD with.
Also, there was talk about attempting to preserve the original aspect ratio of Apocalypse Now, until it was revealed that the upcoming Blu-Ray will be in the original aspect ratio.
Although, to be fair, I wouldn't expect the non-Star Wars preservation section of this site to get nearly as much attention. I mean, this is OriginalTrilogy.Com, not FilmPreservation.Com.
