Final Fantasy Versus XIII may be going the same route as Final Fantasy XIII. According Square-Enix CEO Yoichi Wada, a 360 version of Final Fantasy Versus XIII is in consideration.
While the Xbox 360 version of Final Fantasy XIII didn’t pull in nearly as many units as the PlayStation 3 version, it still pulled in over a million copies (via: VGchartz). Unless Sony pays some major money to stay an exclusive, I can’t see Square-Enix just leaving Versus off of the 360.
Final Fantasy XIV is also a PlayStation 3 exclusive on the console side, but we may see that move to 360 as well.
