actually after some thinking , last year the tickets went on sale without any band announced so it might take a while.
im still standing on that the 1st headliner will be linkin park and it will be announce around november 15th when the new album is released.
Selling out London O2 is comparatively small now?
I mean sure football stadiums are bigger but nice if you can get it to book arenas for your first shows in a while.
