The next Final Fantasy game will be announced at the Final Fantasy anniversary event which is being held from August 31 through September 2 in Shibuya, Japan. According to Final Fantasy 13 and 13-2 producer Yoshinori Kitase, Square's announcement will focus on the Lightning Saga, leading us to believe that next game will be centered around the hard-hitting female heroine from Final Fantasy 13.
Kitase also mentioned that the new project has only recently started, and that Square will announce the project's title at the anniversary event. I'm guessing it will be called something original, like Final Fantasy 13-3.
If a FF 13-3 is announced at the Final Fantasy anniversary event, would you be excited for it? I felt like FF 13-2 was a great improvement on the orignal game and would love to play the third installment. Let us know how you feel in the comments.
