Square Enix have released the one and a half minute Tokyo Game Show trailer of Fabula Nova Crystallis! Within it contains snippets from Final Fantasy Agito XIII and Final Fantasy Versus XIII. The trailer was previously leaked onto the internet but was taken down with frightening speed and efficiency on Square Enix's part. Check it out below, courtesy of GameTrailers.
Square Enix also confirmed an event will be held in January 2011, most likely for the re-reveals of the remainder of the Fabula Nova Crystallis project.
