has been leaked:

Arcade Fire
Kaiser Chiefs
Scissor Sisters
Fallout Boy

Despite the atrocity of Neon Bible, I'll go to the Arcade Fire one, but unless any of the others have amazing support, I think I'll pass.

If anyone has a desperate urge to be guaranteed tickets for it, go on www.edenbookings.com and purchase the thing called Inside Track, it's a tenner, and guarantees you 2 tickets for each show if you want them.
