Pearl Jam, Franz Ferdinand and Muse have been confirmed by NME as the headliners.
The Kaiser Chiefs, Arctic Monkeys and Flaming Lips will be second on the bill.
Dirty Pretty Things and Racounters will be on an unkown stage.

This is from NME but they were spot on last year, so you can probably take it as fact.
Personally I’m not too sure about the large amount of indie up at the top, but am pleased to see Flaming Lips in the line up. Shame about the lack of Alice Cooper and still no sign of Tool!

Update: I am being told that the Pearl Jam rumour is false. I can’t confirm this, but just bear it in mind. Sorry to get everyone’s hopes up.
