Square Enix has just launched the official site for its upcoming PSP title, Kingdom Hearts: Birth By Sleep. In addition to the usual information and screenshots, the site also states that the game will be available in Japan before the end of 2009, which is earlier than many of us expected upon hearing it had been slated for "Winter." Hopefully we won't have to wait much longer than that for our own version.

Among the stuff on display are some teeny screenshots that give us a look at the game's various worlds and stages. These include Snow White, Cinderella and Lilo & Stitch so far. The site also has a "Message from the kingdom" link, leading to the official blog for the series, which at this point contains little more than a greeting.

This is all backed by information on the story and characters (if you can read Nihongo), and a trailer under the movies section. Something to keep an eye on if you're a fan of the series, and we'll keep you updated as newer info pours out of it.
