Take what you guys are saying and follow to its logical conclusion: the shows aren't sold out at all.
Instead, some portion of the total number of tickets has simply shifted from TicketMaster over to third-party heavily inflated sellers.
Perhaps not even "third party" as is the case with the TicketMaster-owned StubHub.
In other words, the shows aren't actually sold out; it's just that some significant percentage tickets went straight to the re-sale market, where they may or may not find buyers.
I don't think adding shows or switching current ones to larger venues is going to accomplish anything, as those efforts do not address the problem.
Seems to me that if more shows are added, it'll just fuel the scalping fire. What they need to do is to remove or revoke the tickets offered by third-party services.
Just my two pence.
