 Bring your parka to the Super Bowl next year because it is going to be cold. The Super Bowl breaks from tradition in 2014 as it heads to a cold-weather city in an outdoor stadium. 
  
 Things will get a little warmer for America's favorite game in the proceeding years. 
  
 The host site for the Super Bowl is only determined through 2015, but the finalists have been determined through 2017. We'll review all four of those years in the following slides. |||||

Don't start placing bets on who will play next year's halftime show: There may not even be one. The next Super Bowl, set for New Jersey's Meadowlands stadium, will mark the first time the big game will be open to potentially frigid temps—and it may be too cold for a performance, according to the New York Post. "It’s not only the acts and the singers, but (also) the crews that have to put the stage together," a planning source explains to the paper. The whole performance is supposed to move quickly, and "you just can’t assemble the stage and break it down fast enough in the cold," the source says. And "there's no plan right now of what to do in its place." It's not just the halftime show that's a problem, insiders say. "There are a thousand things we didn’t think about," notes one. "The NFL is freaking out ... because they’ve never done a cold-weather Super Bowl," adds another. Everything from transportation to postponement policies could cause trouble. Officials are already reserving huge quantities of plows and rock salt, the Post reports. (Click to read about other future Super Bowl sites.)
