Square Enix is readying a new Final Fantasy game, which has been referred to as "Lightning Saga". It's probably going to be Final Fantasy XIII-3: SOMETHING SOMETHING, but as Yoshinori Kitase pointed out today on Twitter, "The title isn't Lightning Saga". Phew!
Rather, Square Enix will be unveiling the game's title at its upcoming Final Fantasy event. Just as long as there aren't stupid weather puns!
