Since all of these shows are "single" shows I don't expect any revolutionary changes to the setlist. I found it strange if they premiered new songs now for one of their last European shows. But, of course, it's not impossible. Overall I think with this tour U2 should play two dates everywhere, because it seems like a huge effort setting up the stage for only one show, and the band is always best if they play two shows in a row at the same place.
However, I'm sure, regardless of what they will be playing, these will be very good shows and people will enjoy them. To everyone who's going, have a great night!
