Yeah, on their official site or their fan site, don't remember which, they say they were never finalized to play, and they will be in New York working on their new album during Coachella, and they don't want to break up that process to play a show, especially when they will be rusty from not having played in a while. Kind of a bummer.
Eron Alkan was taken off, Of Montreal was taken off, We Are Scientists were taken off, Bojones was taken off, Paul Van Dyk and Willie Nelson switched places, the "Radio Bemba Sound System" was added to Mano Chau, Air and Happy Mondays switched places, the "the" on The Jesus and Mary Chain, The Arcade Fire, and The Decemberists were all made full font size (instead of the tiny little font size)...I think those are all the changes so far from the original poster.
the "V" in Paul van Dyk use to be capitalized before he was moved up on the poster. Crowded House and Placebo switched places too, and the section that originally read "Kasier Chiefs, Damien Rice, the Roots" now reads "the Roots, Damien Rice, Kasier Chiefs"...and in fact, that whole third tier of bands on Sunday has a slightly larger font size now. Richie Hawtin was moved in front of Soulwax Nite Versions too.
