For a little change regarding the 5th leg, do you think U2 will replace the ZOOTV encore with a POP encore ? It would start with the slot machines spinning until the evolution of the shopper is complete then blast into Mofo and then Discotheque before finshing with an acoustic version of Staring at the Sun. Plus he has the hair for it now I'm sure it would make a welcome change to the setlist.
