I think they would focus more on the 80s stuff...I don't think much of AB, Zooropa or Pop will be included, but more of Boy, October, War, TUF and Rattle and Hum, B-sides and rare songs..
There will likely be some more recent songs from the last 15 years that might fit in with the tone of The Joshua Tree material, but just have a feeling a lot of the 90s stuff won't be included this tour, just a theory though...
