Last week we gave you an anagram teaser that a GamingAngels reader solved to mean that there will be an announcement Nov Thirteenth. Square Enix has come through with the announcement today.

First, we have a trailer that will show new gameplay footage, interviews with the dev team and a special message from Square Enix, President and CEO, John Yamamoto. We also have a couple new screenshots, and the Final Fantasy XIII website is highlighting three new characters today: Fang, Hope and Serah.

Final Fantasy XIII will be coming to the Playstation 3 and Xbox 360 on March 9, 2010. That’s when I’ll go on a brief vacation.

Microsoft is getting into the action with an exclusive Xbox Live item if you Retweet about the contest. Go to the link first because you’ll have to register first. When the Twitter RT bar is full then everyone that is registered will get the free secret item.

“We know that our fans have been eagerly awaiting the next installation of the franchise – FINAL FANTASY XIII will exceed all expectations,” said John Yamamoto, president and chief executive officer of Square Enix, Inc. “Coming simultaneously to PlayStation 3 and Xbox 360 for the first time, FINAL FANTASY XIII will be available to all players who are looking for the most immersive gaming experience of 2010.”

Here is a glimpse at the story from Square Enix:
Cocoon — a utopia in the sky.
Its inhabitants believed their world a paradise.
Under the Sanctum’s rule, Cocoon had long known peace and prosperity.
Mankind was blessed by its protectors, the benevolent fal’Cie, and believed that tranquil days would continue forever.
Their tranquility was shattered with the discovery of one hostile fal’Cie.
The moment that fal’Cie from Pulse — the feared and detested lowerworld — awoke from its slumber, peace on Cocoon came to an end.
Fal’Cie curse humans, turning them into magic-wielding servants.
They become l’Cie — chosen of the fal’Cie.
Those branded with the mark of a l’Cie carry the burden of either fulfilling their Focus or facing a fate harsher than death itself.
A prayer for redemption.
A wish to protect the world.
A promise to challenge destiny.
After thirteen days of fates intertwined, the battle begins.
