My thoughts:
I'm concerned about how a ported PSP game is going to look on a PS4.
I've asking for this game for a very long time. But I was asking for a PS Vita version because I think it would be better for Vita.
Square Enix said in a recent interview that they are making this PS4 version to ensure that the Final Fantasy fans have migrated to the new generation before Final Fantasy XV launches. A Vita version may be counterproductive for Square if that's their strategy.
