Me three.
If that doesn't happen, I would still buy the audience recording as an FTD. In my opinion, if the Pittsburgh show is worthy of that treatment (specifically, a great audience recording of a historically significant and kickass show previously released on bootleg), then the final show certainly is as well. I have no idea how well the New Years Eve show sold though, and that would certainly be a consideration.
If the soundboard does ever see the light of day and public release in some fashion, I think it would be great if the audience recording could still be utlilized to enhance the "dry" sound that most soundboards have, giving it some room ambience and particularly making the fantastic audience response much more noticeable.
I know everyone would not want that though, because that would make the soundboard recording less "clean". Perhaps that should just be left up to people who have the proper equipment to make their own new mix. Then those who want the best of both worlds--a clean recording which really captures the feel a of a live concert, the way it sounded in the arena (like what we get with professional multitrack recordings) could have that.
...which brings us back to the bootleg market!

Perhaps a DVD would be the answer. Heck, I don't know. It's all fantasy at this point anyway, but if we can dream...
