During an interview, Nomura talked about the state of remakes for the Final Fantasy series. He said that he noted to someone else in the studio that they had remade Final Fantasy III and then Final Fantasy IV, but then jumped straight to Final Fantasy VII. So he pointed back to Final Fantasy V and VI wanting to see those given the same treatment and not ignored. It is no confirmation, but it seems like a strong likelihood that we will be seeing remakes of V and VI in the future.
