I agree that ship has sailed. The improvement I would hope for are more in the realm of including songs that were left on the cutting room floor. I so want the drum duet in the Mama video to go into Los Endos. I don't know if they filmed the other medley on that tour, but I would love to see something beyond the single camera stuff they have released from rehearsals.
I'd love that too, but I'm pretty sure all of the missing songs are on that same ship.
Which is a shame, I freely admit. While there's always a chance something might be discovered sometime down the road (the TSL Bluray was an unexpected benefit of the film masters turning up after the Movie Box was made) I'm at peace with the notion that what we've got is what we're going to get.
