It's amazing that I'm actually the one here arguing for more new stuff and less staples, usually it's the other way round
In Munich it was raining, at least for some parts of the show, and they still played the new and unreleased stuff. I don't really know if weather is a big factor for U2 at all. I understand they play a more or less "greatest hits" set in cities where they haven't played before. I was actually defending this decision for Athens, Istanbul and Moscow when many other people on various U2 boards slammed the band for the "boring" set. I just feel in Brusseles there was no need to throw out all the new stuff, it's a step in the wrong direction, IMO. I hope that when the tour will have reached Australia it won't be a total greatest hits tour. U2 shouldn't stop experimenting with new stuff and continue to show some courage by playing unreleased songs. It was one of their greatest decisions ever to do that for this year's tour.
