So from what I've been able to gather this is the stage that's been uploaded to the Heinz Field stadium in Pittsburgh.
There will also be a pre-sale for those who sign up on her website from Nov. 11-15.
As far as ticket prices go, not many sites have uploaded much info, but they indeed do begin around $50 and go upwards to $100 or so. I forget where I saw it, but at one point i did see tickets to be up to $384 so I'm guessing that would be a VIP package.
