This "leak" is silly. Nothing really lines up. The only thing that could possibly come out of this is that we get a Directors Cut of the game when the PC Version releases.
One would assume most of the Dev team for this will be moving on to help with FFVIIr (Looking forward to that, never played the original), and the small team will be left for DLC and patches for this. Then once FFVIIr is coming together and the first part or so is out, we'll start hearing rumours of FFXVI and KH3 will hopefully have a release date.
That's more likely to happen than some stupid Versus FFXV.
