The first post is kept pretty up to date with what’s included. Really the only thing not listed is audio, which for Disc One will include the three DTS-HD-MA tracks (5.1, 2.0, and 1.0).
Discs Two and Three are still in their infancy. I’m still trying to gather the necessary tracks for them, so until I finish Disc One, not too much will be said in terms of technical details for them.
