*if it sells well.
Anyway, as someone who only got into the franchise with XI, one of the elements I liked the most was the classical JRPG feeling combined with the nice production values. So it would be a shame if they completely leave that behind in order to turn it into another action based JRPG of which there are many. Though I wouldn't mind adding some new twists to the combat. Some sort of ATB Gauge, or positioning being more important, or maybe doubling down on the combined attacks, etc.
