Yes, it is a tad ridiculous that we've now gotten this and yet still no remastered OOT. Lucas doesn't actually own the distribution rights to any of his movies, he just owns the rights to the movies themselves (and even that isn't true of THX and Graffiti). At digitalbits I've read a transcript of a chat with someone from Warner Home Video and they actually said THX might get a blu-ray release as early as this year. GL wouldn't have any say in that. Even if he owned the rights to the film itself, WB owns distribution.
It actually begs the question of why 20th Century Fox didn't/doesn't just take the best surviving OOT film elements from their own vaults and put out a decent set themselves. Does this all stem from GL's renegotiation of terms back in the mid-90's?
