I dunno, I'm the guy who sees no point in buying the BluRay sets that are just slightly better than my current DVD sets. My Trek experience really isn't going to be enhanced by being able to see their zippers better or slightly beefed up graphics. The cut scenes/outtakes and other extras are interesting, but will end up on youtube anyways.
And as mentioned, I'm sure there will be another edition some years down the road anyways. Lucas seems to have known what he was doing in re-releasing it every 10 years or so with new editing to generate sales.
