EA SPORTS has been very consistent in their release date for the NHL series. I fully expect NHL 13 to be released on September 11, 2012. The team at EA SPORTS is usually tight lipped about the release date of NHL 13 this early in the year, but they have always been able to hit their second Tuesday in September release dat target in the past. Gamestop is currently listing the game as being released on 9/11 as well.
