Square Enix have announced a release window for the Western version of Kingdom Hearts: Birth by Sleep. Only the North American release has been confirmed by Square so Europeans may have to wait a little while longer for news of their release.

Square Enix confirmed the summer release window on their North American site, where it states:

LOS ANGELES (March 16, 2010) — Square Enix, Inc., the publisher of Square Enix® interactive entertainment products in North America, announced today that KINGDOM HEARTS Birth by Sleep will be released in North America this Summer. Coming exclusively to the PSP® (PlayStation®Portable) system, the game is a prequel that reveals the untold origins of the popular KINGDOM HEARTS franchise.

News sites have broken out with confirmation of the European release of Birth by Sleep but Square's European website has had no news on the subject. Kingdom Hearts fans can now take solace in the fact that Birth by Sleep now has a release window and the waiting is almost over.
