Alright, I missed that. But they didn't have a deadline or anything, right? So maybe they've just gathered the footage and will do something with it in the future (some extras for the Bluray release like hoserama suggests sound great).
They've got plenty of footage on their own of the Roxy show, both audio and video. I'm sure the fan footage was icing on the cake if they intend to release something from it.
I have hard time seeing them release the whole thing, but agreed, would be awesome. I still wish they had played An Cat Dubh + Into the Heart like they soundchecked.
