I'm going to laugh if the Tool dates are fake. Ticketmaster sometimes posts fake dates. They posted a whole Hank III tour a few years back, sold tickets and then it turned out that the tour was fake. Tool's website has no information about this tour. Mandalay Bay's website does not mention anything about Tool playing. I would have expected some sort of announcement other than random dates popping up.
