Square Enix Europe has surprisingly announced that Final Fantasy XIII will be attending GamesCom, a convention being held in Cologne from August 19th - 23rd. It's the first time FFXIII has appeared at a European gaming convention and is a pretty welcome announcement for most of us assuming TGS would be the next time we'd see any new Final Fantasy XIII info.
At the moment, we're unsure what form FFXIII will be presented in but there could be the possibility of a new trailer and maybe a playable demo, most likely the old one. No mention of any of the other Fabula Nova Crystallis turning up which is a disappointment but there's always TGS.
