I'd say you're pretty cold at least for this year, cause Glenn doesn't book bands 2 years in a row.
edit: the more I think about this, the more different bands come to mind...anyone else notice slot #1 is *not* one of the 6 US debuts? So what band has played the US before but not Progpower? Someone mentioned Running Wild, which would rock but I think I remember reading before that Glenn said they asked for too much money...two bands I can think of off the top of my head that could fit the criteria here are Grave Digger (crossing fingers) or Helloween. I'd actually have to lean more towards Helloween only because I couldn't imagine any other band getting a higher billing than the 'weenies. They aren't my favorite band by a long shot, but holy shit do they put on an amazingly kickass show. I saw them twice on the Rabbits tour, and they're one of those bands that if I hear they're playing somewhere and I can make it to the show, Im going.
