Mine arrived today.
The packaging makes for a cool collector item, the book being the case and not a separate item in the pack is a little dissappointing, be nice if you could have one without the other for whatever your purpose.
As far as the music on disc 2, great to have proper cuts of cues that didn't make it onto disc one, particularly, the bit from the end of the film when Batman throws Joker out off the Prewitt building, I've been very vocal about how I love that cue and I'm so glad I have it now.
My only dissappointment with the music accross the 2 discs is that it's all over the place and in order to have a chronological score, I'll have to cut some tracks and blend some together with my software, which is ok, I have fun doing that an all, but it can be a bit of work, and I'd have loved if like the Star Wars Episode 1 Ultimate Edition, it was just every second of music from the film from start to finish. I wish all film scores were that way.
