Has everyone forgotten about Andromeda?! Their new album will probably be out in early Spring. PPVI would be a perfect chance to tour it. I like the Magnitude 9, Sonata Artica and the Pyramaze. However, I'll have to chime in a vote for Opeth as well. My GF will NOT miss PP if they play! I'm not sure if they 'qualify' so to speak... They'd make a nice Headliner.
