Are Slipknot and Disturbed going on tour?

I heard they be this summer, but I don't know anything else about it, or if it is even true. Does anyone know anything more or less it?

Answers: I also do not know anything else about it.

"Slipknot and Disturbed will hit the road this summer on the first ever Rockstar Mayhem tour, Billboard.com have learned. The outing, sponsored by Rockstar Energy drink, will run within July and August, with more artists and dates to be announced."
