So last gen for the XIII series the engine that Square Enix used took a ridiculously long time to develop and the PS3 was a disaster to develop for in the beginning to to mention the whole fiasco with XIV which led to ARR being made, so i've been wondering, with the PS4 and XB1 being easier to develop for and if the engine for FFXV is flexible enough to be reused, could we see more Final Fantasy games this generation compared to last gen where we only gotten 4?(6 if you count X/X-2 HD)
