Tickets on sale when I'm abroad (I'm assuming this sells out in minutes), and the actual dates could not be worse for me work-wise. Still going to try to get tickets, of course, but god damn!
I'm personally confident that Slipknot will be one of the headliners next year (no insider info just lines up with them likely releasing an album soon)
Then there's the headliner that's never played the festival before which the bookers have alluded to so that's one of Blink, Foos, NIN, Nickelback and possibly Pearl Jam or even Bon Jovi
The third band I also think will be a new headliner who are being bumped up so Deftones, Offspring, Paramore Etc.
I'd love Slipknot, Foos and Paramore but realistically i'd go with Slipknot, Blink and Deftones
