I mean, sure. But I don't see this being a new development for a band that was charging $250 for seats during the last couple of tours. All of their tours are about money. Not just this one.
I see the OP as a way to de-legitimize this tour compared to the "it's all about the art, maaaan" view regarding their previous ones. I think this tour can be every bit as artistic and, yes, entertaining, as their previous ones. Just like a classical concert, consisting of material 100's of years old, can be a moving experience without playing a single "new song". I'll judge for myself when I see it. If them not touring new material is a turnoff--and hey, I get it, not everyone will be into this--fair play.
