No offense to you Zombie fans, I hope it's not a Slayer/Zombie tour. As a Slayer fan, I'd like to them headline, and I'm sure the Zombie fans want to see him + his band headline. If they tour together, it'll most likely be a bullshit co-headline deal, where they each only get like 60-70 minutes.
08/30: Bane and tour (?)
10/15: Soilwork, Decapitated (?)
