Okay, folks at Joystiq have reported that Square Enix's president Yoichi Wada has annouced that Final Fantasy XIII will be released in Japan on December 17, 2009. It will retail for ¥8,800 (rouchly £58 or $95 US).
A PS3 hardware bundle with the game will come out, though Kaz Hirai doesn't tell of any info such as pricing or a date when it arrives though.
In any case, we know it's finally coming, now we just need a western release date for the game - if it does happen to differ to the Japanese launch that is.
