You know that Tetsuya Nomura guy? He kinda makes games. Thanks to Andriasang.com, Nomura tweeted out of nowhere about Final Fantasy Versus XIII.
The Versus XIII director wrote this on the 3rd Birthday Twitter, "Multiplatform is when you start development on a game with the assumption of optimizing for multiple platforms. Porting is something that's done after you've developed a game specifically for a particular platforms. The debate over porting is decided by the management based off the current market and the costs. All I can say right now as a developer is that Versus is being developed specifically for the PlayStation 3."
