I would be extremely suprised if U2 did less than four shows in Boston and NY/NJ. A lot of these arenas will need to make up revenue due to no NHL. Four nights of U2 in Boston and New York are four guaranteed full houses. Will the promoters/band leave that money on the table? I would think that this tour, would follow the Elevation pattern rather than the Zoo Tv pattern. The band is that much older, so the wears and tears of travelling are more pronounced. Also April/May/June would mean a more practiced show, rather than the second week of March. If you listen to the boots from Elevation, they sounded much more crisp/practiced in the May June shows, than the March/April shows. You saw songs like Party Girl and 11'O Clock pop up during the later months that you didn't see in the early months of the tour. I saw them in Miami the last time, and they were great, but the June shows in Boston were 10 times better. My bet, late May and June, when you really have the open arena dates.
