Square Enix director Motomu Toriyama hasn't told PSM Australia anything other than what we've already known: Fabula Nova Crystallis Final Fantasy XIII is a collective of projects that has never been declared exclusive to one platform. Yet, when Toriyama suggests that Fabula Nova Crystallis "isn't just limited to three titles" and that "it's not simply exclusive to the PS3 and mobile phones," so many of us are willing to take a leap of faith, heralding these words as a death knell for Sony, and as a confirmation of FFXIII on Xbox 360. Before you join the feverish mob, remember to draw a distinction between the primary game, currently exclusive to PlayStation 3, and the general series, already totaling three titles (Final Fantasy XIII, Final Fantasy Versus XIII, and Final Fantasy Agito XIII) and at least one loose logo, Haeresis ("Dissidia" is also possibly linked to FFXIII).
Toriyama has merely reaffirmed that, like Final Fantasy VII, the FFXIII brand will be spun into an array of disparate shards, conveniently linked by a popular title. We may yet see a spin-off on 360 -- or even a port of the PS3 games -- but don't jump to that conclusion based on the PSM interview. Yes, we've still got Haeresis (and possibly Dissidia) without a home, but either DS or PSP, or dare we say Blu-ray, DVD, and UMD, are just as valid destinations as Xbox 360 -- don't count out PlayStation 2 or Wii either. Given all the fuss that Final Fantasy rouses, Square Enix would do best to deliver on all of 'em.
The moral is: Final Fantasy XIII -- the game -- is still exclusive to PlayStation 3.
