While an official number isn't known, the advance for Wrestlemania 27 next year in Atlanta appears to be the slowest in years when it comes to ticket sales. Nearly a week after tickets went on sale, you could still get 10th row ringside seats (these are the $850 priced seats). There are also plenty of tickets available all around the Georgia Dome at various prices. While there isn't any fear within WWE that they won't have a huge audience for the show, tickets definitely moved a lot slower than in the past few years where you heard of "sell outs" within minutes, a half hour or hour. Were told the cheap seats are all sold out after a check with Ticketmaster.
