More info from my 2nd source in the OP....
At its DK Sigma 3713 event in Japan, Square Enix has revealed that it plans to release a playable PS3 demo of Final Fantasy XIII in March 2009. According to a GameSpot report the demo will be bundled with the Japanese Blu-ray release of Final Fantasy VII: Advent Children.
The demo disc will also include new trailers for Final Fantasy Versus XIII and Final Fantasy Agito XIII (mobiles and PSP).
Square Enix also confirmed that Final Fantasy XIII is scheduled for a worldwide release sometime in 2009. How close this date is to the March demo is unknown.
