With Thunderstone announced, it'll be really hard to guess that Saturday #2 spot because its between a heavy prog band and a traditional-ish power metal band. Perhaps Adagio makes the number two spot and breaks the two year rule?
As for the headliners and number 4 on Friday, I'm gonna put my money on Freedom Call as #4 Friday just cause I want to see it happen so bad. Follow it up with Evergrey and call it a day.
I don't like em, but I think it's inevitable that Helloween is gonna nab a headliner spot. Pisses me off, but w/e.
