OK, I realized that I never really responded to the questions about what kind of bonus material there will be on the disc. The reason is that while I do have some things in mind, I don't want to give away too much, because I'm not sure I'll be able to do them all.

What I definitely want to put on the disc are several galleries:

This v1.0 changes gallery

An updated version of this v1.0 vs Remastered gallery

An updated version of this gallery of all changes showing BD vs GOUT vs v1.0 vs. v2.1 (or2.5, depending on whether there is a v2.5).

An updated version of this v2.0 vs. v2.1 gallery with some descriptions added.

There will probably also be a video version of the third gallery, showing the changes in movement.

I'm also working on a commentary for the whole film, though I'm 30 minutes in and already running out of ideas for things to say, so we'll see :-)

There's some more stuff I have in mind but I'm not sure I'll be able to pull it off.
