In a recent interview with Eurogamer, Tabata has mention he will be making the gameplay a more casual experience.
"Another example is in the combat," explains Tabata. "With the hardware specifications of the newer consoles, it's possible to set it up so you have different enemies and different choices of attacks you can enter in, but I want to simplify that. It'll basically be a one-button action, and the AI intuitively outputs an action that kind of satisfies, gives you that instant gratification, and it connects with the simple touch of a button. I myself am not getting any younger. I don't want to be frantically pushing buttons. I also want to utilise the intelligence of the hardware spec, and not have to go through too much hassle or trouble in order to execute moves."
Displeased FF fans in Japan however, have already starting a petition to bring back the original combat system.
