The Washington DC premiere went on sale last week, while Boston and Philadelphia are next to hit the box office. Both events will go on sale on Friday, August 16 at noon EST. Lowest-cost tickets are listed at $20, "not including facility fees & service charges".
Boston's event takes place on October 9 at the Agganis Arena, which holds approximately 7200 fans for concerts, and a shade over 6000 for hockey games. Impact Wrestling's Slammiversary 2013 took place at Agganis Arena, and drew 3800.
The Philadelphia show runs October 16 at the Liacouras Center, a building which houses about 10,200 fans. Impact held two pay-per-views in the building: Lockdown 2009 (drawing about 4500) and Bound For Glory 2011 (about 3600).
The show premiere at Washington DC's Capital One Arena sold 10,000-plus seats in a span of two to three hours. An additional 3000 seats have since been made available, and Dave Meltzer notes in The Wrestling Observer that the venue is now set up for 14,000 fans.
