Ticket prices are generally based on the costs to stage the event and run the organization. I expect them to go up a bit (because prices on everything have been going up lately), but not to ridiculous levels out of the gate.
The org always teeters on the fine line of what is a fair price, what will the market bare, what can their target audience afford. I predict that the tickets for 2012 will be starting at $230 next year and work their way upwards. I also think that there will be more preparation and people will be buying their tickets much earlier than last year. The interesting part of that is that there will be a large number of people flaking out at the last minute and needing to sell their tickets. Next year will have a huge glut of tickets toward August and the scalpers will be screwed.
