The theme song for Final Fantasy XIII has already been ripped (from the radio apparently) and thanks to a livejournal member, you can hear it below in full. Kimi ga Iru Kara performed by J-pop artist Sugawara Sayuri is set to be released as a single on December 2nd in Japan and the Final Fantasy XIII OST is coming out January 27th 2010.

The Japanese Square-Enix store have updated their site to reveal the Final Fantasy XIII box art which confirms that the other one floating around recently is indeed fake. It's basically just the logo, it could just be a place holder but it's the same style we get every time here in Europe. Nevertheless, enjoy.

The lastest issue of Famitsu (either Weekly Famitsu or Famitsu PSP+PS3 according to our beloved Shuyu) has revealed that Final Fantasy XIII's lead role Lightning will be appearing in Dissidia: Final Fantasy. Small photographs of the magazine have appeared on the internet which look legit, but we'll update when/if there is some proper confirmation. It's also unclear how this will be added. Presumably it will be DLC or be a bonus in the "newer" version being released in japan but without being able to read tiny blurry writing or even Japanese to begin with it's hard to tell. We'll keep you posted.

Update: Turns out it is
fake. Someone over at Dissidia-France did it as a "Halloween Trick". I thought this was more of an April Fools sort of thing but props for the effort nonetheless.

Square Enix's official Final Fantasy XIII website has been updated to include more pages of the Final Fantasy XIII Novel, more information on
Oerba Yun Fang as well as some new screenshots of her which aren't that exciting. As for the summons, an update in the Summon section now shows profiles for Bahamut and Brynhildr as well as a few new screenshots.
Translations will probably come shortly.

Official Playstation Magazine UK have laid a small 4 page spread bringing anybody over the pond from Japan up to speed with the latest Final Fantasy XIII news.
But like anybody who uses the internet, most of the information is mearly just a repeat of what has been shown on most Final Fantasy news sites already; yet it is a nice informative preview on the Character summons and also an introduction to that of the new members which sit on the Cast list.
Enjoy.

Several Japanese online retailers have just put up a listing for the Final Fantasy XIII Soundtrack which is set to be released on January 27th next year. It's of no surprise that one would be coming and it seems Square is keeping it's tradition of releasing them a few months after the games launch.
The OST will be released as a 4 CD set to accommodate the huge amount of tracks the game includes. The first pressing will be a special edition which will also include a fifth disc which is apparently going to be a drama cd. The soundtrack will cost 5250 yen.
