Well, at least for the Japanese arcades. King of Fighters XIII
will be launched in the Land of the the Rising Sun on July 14, 2010. The new game will continue the storyline started in KoF 2003 and XI as well as include a plethora of new gameplay features such as Hyper Driver Mode.
Unfortunately, we are STILL waiting on information regarding a possible north American, or worldwide, release. Surely it has to happen by the end of the year.
