About the only special features from the 2007 Gold Box Edition that aren't mentioned in the official press-release are the SNL sketches and the Japanese coffee commercials, but early details can frequently be incomplete. We'll see what happens, here.
Turns out the vast majority of the extras from the previous CBS and Artisan DVD releases were indeed carried over into the Blu-Ray set (none of which made it onto the Gold Box edition), largely contained in "The Glastonbury Archives" section on Disc 5, as well as on Disc 6.
Only the Artisan director's commentary tracks are omitted from this Blu-Ray set (at David Lynch's express behest, as it turns out). Apart from the SNL sketches and Japanese coffee commercials, this BD is a remarkably comprehensive release.
