Everytime there's a new FF game it's speculated that Squenix might make a multiplatform release.
This time, well, I don't have anything concrete, but since 11 was an ok success on PCs and 12 is based on the same world, not to mention there being an established fanbase that's still fairly active, a PC translation isn't such a huge stretch. As to whether it's gonna get to us westerners, we'll see.
