There hasn't been any announcement concerning that. However, it has been extremely well-recieved and extremely successful. The manga has also seen a major increase in sales, so I wouldn't be surprised if they made a second season.

However, it would probably not be until late 2014 at the earliest. They've covered roughly 32 chapters of material in 25 episodes, and we're currently waiting for chapter 50 to be released at the beginning of next month. So they don't have enough material for a second season, unless it was 13 episodes instead of 25/26.
