This article goes to the person who commented I did not know what I was talking about. Look at the headline. You know who you are. I'm rarely wrong (cough) and in this case Square Enix have announced a sequel to Final Fantasy XIII called Final Fantasy XIII-2...

Or to say it phonetically , Final Fantasy Thirteen Minus 2. See, I know what I am talking about.
