With Chael Sonnen's destruction of Brian Stann at UFC 136, it was obvious a rematch with Anderson Silva was the only option for the next championship fight. Aside from perhaps Mark Munoz and Michael Bisping, Anderson Silva has completely cleaned out the division, and a fight with Sonnen is one of the few remaining compelling matchups the UFC can make.
With a successful show in Texas, MMA Junkie reports that UFC President Dana White has been in talks with Dallas Cowboys owner Jerry Jones in regards to putting on an event at Cowboys Stadium in Arlington, Texas. The 80,000 seat stadium would easily surpass the 55,724 record at Toronto's Rogers Centre, but the UFC hasn't exactly proven to have that kind of drawing power—at least not in Texas.
It would also make sense to host another event in Brazil, given the demand for seats at UFC 134 and the hatred for Chael Sonnen. The last event in Rio de Janeiro was in an arena that held a mere 14,000 seats, although there are several stadiums in Brazil that hold well over 60,000.
Finally, if the UFC wanted to truly make an impact in Japan, it certainly could go for Nissan Stadium in Yokohama. The stadium has hosted several FIFA World Cup games and has a total of 72,327 seats. The Saitama Super Arena is set to hold the UFC's next trip to Japan on February 26, 2012, and has a reported capacity of 37,000.
Either way, Silva vs. Sonnen II is certainly going to be a major event. Particularly with Sonnen's post-fight hype at UFC 136, the pay-per-view buy rate is likely to be in the top 10 for the organization.
