If thas what you mean by direction I don't think you have anything to worry about.
If there is one thing we can say about the FF series its that its one of those series that continues and always reinvents itself. No matter how successful its previous installment was.
But I dont think that Square would see turn based combat as an reinvention or "moving foward".Dont have much faith in them regarding FF, given that they havent done a great FF since FF XII(excluding XIV of course, since that game is an MMO)
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
