Square-Enix has had problems in the current gen, I suspect that the company couldn’t adapt Final Fantasy and other IPs to the HD era. Moreover, the first version of FF14 was a downfall, this game forced to stop the development of other games to focus in the rebuild of FF14. Really it’s like a new game.
Square-Enix announced Final Fantasy Versus XIII years ago and the game was lost in the limbo. Square decided to halt Versus PS3 development two years ago, but the RPG wasn’t cancelled, why? Two years ago, Square-Enix moved the game to PS4 and Sony got in the project.
Actually Sony is co-developing the game with Square-Enix, therefore, this game will be exclusive on PS4.
Square-Enix renamed Versus to Final Fantasy 15 in the middle of this process. Sony’s studios are helping SE with FF15 assets among other tasks.
We hinted this PS4 exclusive one month ago, but we couldn’t speak freely about this topic. Now, it’s all that we can say.
