Once again, wishful thinking. We'll be lucky to get 5 new songs off the new album live on a regular basis.
For Zooropa, they tried Zooropa and Babyface then quickly canned it. Then they only did Lemon, Daddy's Gonna Pay, and Dirty Day in the Australian legs. So the only regulars were two songs - Numb and Stay.
For POP, their regulars were only Discotheque, Mofo, Staring At The Sun, If You Wear That Velvet Dress, Last Night On Earth, Gone and Please for a total of seven songs.
For ATYCLB, their early setlists didn't have Kite. Their later setlists didn't have In A Little While. New York missed a few European shows if I remember right. Wild Honey was done later and acoustically. Peace On Earth and When I Look At The World were only done in snipper form. There were only four "regulars" - Elevation, Walk On, Beautiful Day, and Stuck In A Moment.
So (2+7+4)/3 = 4.333333. So U2 averages only 4.3 songs from new albums that make it as "regulars" on their tour setlist. So for the next tour, I'd say 5 songs off the new album is wishful thinking. I'd expect 4 new songs, and 1 song from Best of 1990-2000 - then the rest will be rehash of older songs that have been setlist regulars in their previous tours (meaning less learning curve to relearn it). I mean if U2 cared about practice and rehearsal a little more, they ought to spend spend the extra time learning an extra new song from the new album then digging out and old obscure classic that is only a favorite among hardcore fans. Let's be realistic and not live in a dream world.
Cheers,
