Agreed.
Rush did one for every tour this century, but to me, that was making up for the fact that they only had three concert videos for their first 16 albums (none of which were whole shows, and two of which were only about an hour long), so I doubt anyone had a problem with that, especially since the set lists were usually radically different from tour to tour following the R30 tour (outside of the handful or so of usual suspects).
As for SW and PT, I guess I tend to be in the minority of people who think his live stuff, while good, rarely approaches the awesomeness of his studio recordings. That's not to say I wouldn't have loved a DVD from The Raven tour (since that was like a perfect set list).
