Another thing is this isn't a barebones live show where he doesnt have to pay a lot for production etc. I am sure this is costing TR a lot for the production and the additional band members (backup singers, Pino etc). Not selling out the shows could have an effect on future tours, and if he wants to go through the trouble. As for the prices being too expensive, Depeche Mode tickets are even more expensive and they are playing the same arena's and selling out without a problem
