II don't think it's just Maiden. Where I live advance sales for Priest 50th Anniversary tour was horrid, but filled out pretty well come showtime. Advance sales for them aren't so great right now. I ended up not going but I also saw that advance sales for Pantera were very poorl. I know it's just a few more examples but I will say again - disposable income has taken a hit in the US over the last couple years.
