According to @U2 (bookmark this site asap). Go down to the January 20th Headline, "HEAR DAN LANOIS TALK ABOUT THE ALBUM AND TOUR". They link you to Exploremusic where they have an audio interview with producer Daniel Lanois and he gives the goods on the new U2 album and tour.
U2's stages have always been revolutionary and in an economy where many people may think twice about shelling out $100+ for a nosebleed seat, U2 is at least attempting to bring the show closer to its fans. Now whether or not this is for the Euro tour or the US tour, it's not said. But I'd be thrilled to see U2 in a stage configuration that makes every seat in the house a good one.
