Tetsuya Nomura, one of the main guys over at Square Enix, has long been promoting a Fabula Nova Crystallis event, which he said was planned for January. He's stated that the event will be primarily to show the world more about the Fabula Nova Crystallis series, specifically Final Fantasy Versus XIII and Final Fantasy Agito XIII.
That event has now been dated for the 18th of January, 2011. But it's also had its name changed to: Square Enix 1st Production Department Premier. A rather long-winding name for an event.
There will apparently be two showings happening throughout the day, and fans are more than welcome to attend the events too.
