Yeah this is mostly speculation. I think you're a pretty reliable source (you just called the Korn/Disturbed tour a week ahead of time, not to mention some tours last summer), and you word everything correctly so that it doesn't sound like you're making up rumors though.
I think Wolverine makes up for a couple people on this board. I'm not saying any names, I'm just saying Disturbed's latest album and a certain South American band/sex position.
By the way, why won't LOG be on this tour? Headlining summer tour or in another package/festival?
