As stated before though, I don't think this is the last we'll see of these movies on DVD.
A quote from George Lucas himself" "Now we'll find out where people really wanted the original or whether they wanted the improved version. It will all come out in the end." Plus, this is George Lucas we're talking about here. The man seems to have a genetic inability to release only one version of his films. Remaster OOT discs with 5.1/2.0/mono=more money. I highly, highly, highly doubt that we won't see a high quality release of the films in the future, probably the near future with the 30th anniversary so close at hand. Then, maybe, one Lucas sees that there is a market for the version of his films which the majority of fans actually like, then maybe, at some point before the end of time, we can see a high-quality release of the original release of THX 1138 so that I can finally see the movie.
