^Exactly. And they jammed it in between tours where they were actively promoting new material. That's not a nostalgia act. And let's look at the prior 4 album cycles:
-ADTOE: They played the entire album.
-DT12: They played the vast majority of the new album.
-TA: Double album, and they still played the entire thing.
-D/T: First leg, they played between 26 and 30 minutes (4 songs) from the new album. Second leg, they upped that by adding another song over over 9 minutes.
Bottom line is, they still put out new music, and they actively promote it. This isn't, say, Queensryche, where they tour on the classics, and even though QR put out new albums, the sets are built around the hits, and you get 2, maybe 3 new songs tops at a show.
