Man, I'm totally down for this one. I only physically own the expanded Raiders soundtrack they did back in '95, and this has got four unreleased Raiders tracks. (Although I do have stolen MP3s I found on the internet of the Temple of Doom and Crystal Skull soundtracks.) What's most exciting to me is the expanded score to Temple of Doom--that's got some great cues on it. Have never had a copy, legitimate or otherwise, of the Last Crusade soundtrack, so I guess I'm looking forward to that one, too. (So glad I never actually bought the Crystal Skull disc.)
Anyway, this looks like a fantastic set and it's about time the scores from these movies got the attention they deserved, so that more people can enjoy them in their expanded form. (Incidentally, aside from the smaller packaging, this set really reminds me of the Star Wars saga box they released in 1993.)
