The grain issue is not an inherant part of the Star Wars neg per se. It may be that the print used in the DC indeed is pretty grainey, and that this was softened and muddied in the LD but then sharpened and made explicit for the GOUT. Whatever the case, however, one can see that many other releases with a much sharper image than the DC (ie no DVNR) do not exhibit nearly as much grain, nor was such a high level ever seen in any theaters--its purely a print thing. I can't fathom that Lucasfilm would actually add grain to the image, if only because that would require effort on their part, which goes against the entire philosophy of the GOUT.

As for the gate weave being digitally added to the "original crawl" i must strongly disagree with this, for the same reasons that the "fake grain" issue seems dumb. If the original crawl is actually the original crawl then it would suffer from all the age artifacts that produced gate weave in the telecine of the rest of the film (ie enlarged sprockets, swelling, shrinking, dirt and knicks). The original crawl would actually be much older, since the GOUT print for the rest of the movie is some kind of nth-generation print (which would explain the high grain) and not a first or second generation print as the original crawl would probably be from.
