Square Enix just revealed in the latest issue of Shonen Jump (via Siliconera) that a sequel to Dissidia: Final Fantasy will arrive on Japanese PSPs sometime in 2011. Titled "Dissidia Duodecim: Final Fantasy," the new fighter was created specifically as a challenge to website copy editors.

Outside of FFIV's Kain and FFXIII's Lightning, no other playable characters have been confirmed. We get the feeling you'll see an expanded roster of fan-favorite brawlers at next week's Tokyo Game Show.
