They will play the full album. There is no reason for them not to and all of the promo materials have stated that that is exactly what they intend to do. I think the concern with the I&E tour was that they wouldn't be playing enough of their hits at every show if they spread them over 2 completely different setlists from night to night. Ultimately it sounds like they got cold feet worrying about whether an arena full of many (mostly?) casual fans would respond to a set that didn't include enough of the requisite hits on any single night. That really won't be an issue on this tour. The Joshua Tree is their most successful album and 4 of the 11 songs have been regulars in their setlists ever since it was released (Streets, I Still Haven't Found, With or Without You, Bullet). That leaves plenty of room for the 7 lesser played songs on the album plus a whole bunch of other classics and some deep cuts from other eras. They clearly got cold feet last time about having to pick which of the 2 nights would get One or which would get WOWY, but this go round they can play all of the big hits in one show and still have room for some other stuff as well.
