"I'm not saying no to Pittsburgh, but we're going to Philly this year." - Dana White
With New York still dragging their feet, a UFC show in Philadelphia will be a major event for the company and the area. They have expanded into most US markets, but the North East remains largely untapped. Philadelphia will give them a location which is accessible from multiple states who are all craving attention (PA, NY, NJ, MD, DE). Imagine Brad Pitt walking into a bar full of ugly chicks and you have basically what will happen when the UFC comes to Philly.
