Kingdom Hearts: Birth by Sleep was released in Japan last month, but although Square Enix had confirmed that this PSP exclusive will be coming to North America, they had never specified when. That is, until now.
According to the latest edition of Game Informer magazine, the game now has a provisional release window of Summer 2010, which means it will likely see a release during the months of June and August.
Currently there's no word on a European release window, but it's sure to be around the same time as the North American release, if recent games are anything to go by.
