During an investor meeting in Tokyo, Square Enix president Yoichi Wada indicated that the company is considering a multiplatform release for Final Fantasy Versus XIII. An attendee asked Wada about the possibility of putting the currently PS3-exclusive Fabula Nova Crystallis game on Xbox 360 like Final Fantasy XIII, in order to boost sales outside of Japan, to which Wada responded (according to Andriasang's translation) "We'll be looking into it internally until right before the formal announcement."

Wada did not mention when that "formal announcement" would take place. E3 is coming up, so it's entirely possible Wada is building up to that, having expressed his hope for an E3 unveil previously. But we've given up on expecting this game to become real any time soon. When it stops existing only in secret trailer form and becomes an actual, playable game, we'll be shocked, regardless of the platform (or platforms).
