During the presentation of the recent release of Final Fantasy V for mobile devices and the announcement of Final Fantasy IV: The After Years for mobile devices Takashi Tokita had a little surprise at the end of the presentation. Final Fantasy VI will also be released on iOS and Android devices this Winter.
Final Fantasy VI will not be a straight port, but a remake in style of previous Final Fantasy releases for mobile devices with some enhancements. Like the battle system has been adjusted so you don't have to fight as much and can enjoy the game for what it is. The graphics will be optimised for mobile devices but are still in 2D.
At the end Kotaku asked Tokita if games like Final Fantasy VII, VIII, IX or X will be included in the Legacy series. "If this Legacy project works out well, we would like to one day be able to work with VII."
