All FF's have been successful minus the spin offs, I think they're just more interested in milking what they have then producing new content but it seems they had an internal change with that when they cancelled FFXV DLC.
I mean it could have been like last gen when we got XIII, XIII-2, XIII-3.... But we at least got FFVII part 1 & FFXV. I'm hoping next gen they do the unthinkable and release FFXVI & XVII in the same generation.
