It might be too much to ask, but I would have thought something like this is about due:
Original Album Mix Remastered
2012 Album Remix
This would feature a "heavier" more rock driven mix, based on Bowie's comments regarding the "polite" nature of the album. Something like what was done to Moonage Daydream.
The Complete BBC sessions.
Single Edits, and the Complete Arnold Corns Releases
Outtakes, Demos, and Material from the Ziggy Musical
Another complete show from the Main Man vaults. Boston?
The two album mixes in 5.1
The complete Ziggy Era Music Videos and TV spots
A montage of Home Footage taken by Bowie, Mainman, and Bowie's friends.
A documentary on the recording of the album.
A documentary on the costumes, make up, and hair.
A documentary on the character, Ziggy Stardust.
A documentary on the many narrative interpretations of the album, and the abandoned musical.
The Mick Rock Films from the Rainbow show and anything else he shot.
Packaged with a hardbound book featuring essays, the Mirabelle Diaries, pictures of the different sleeve artworks, and of course, Mick Rock photos galore.
