In related news, Final Fantasy XIII Versus is under construction, and may be heading for a multiplatform release.

Despite all press, official announcements and trailers pointing to to FFXIII Versus being a PS3 exclusive, Square Enix CEO Yoichi Wada has said that the possibility for a multiplatform release is being considered.

Wada said, “”We’ll be looking into it internally until right before the formal announcement.”

Presumably, ‘formal announcement’ refers to a proper unveiling of Final Fantasy XIII Versus, which could hopefully roll around at E3.
