In case you haven't noticed, not a whole lot of Final Fantasy games are on the PC at the moment, even in port form years later. But it seems as if Square Enix is coming around to the idea, and we may even see future Final Fantasy titles launch on PC alongside of consoles.
In regards to bringing the XIII trilogy to the PC years back, Final Fantasy producer Yoshinori Kitase had this to say, "As far as the technology is concerned, it would have been possible for us to make a PC version, but we decided against it for two reasons: we looked at the market situation and we didn't think it would be a good idea, and also it would have involved lots of complex issues like security. So we decided not to do it this time around."
But he is hopeful, going on to say, "But we see potential in it and there are lots of regions and countries where PC is very strong. So in terms of our hope of being able to deliver our games to every single country in the world and to as many gamers as possible, yes, we would definitely be interested in pursuing that route in the future."
So yeah, we could easily see Final Fantasy XV on the PC, possibly at launch. Kitase also notes that the FF VII and VII ports are "quite popular," which of course means they're possibly working on a FF IX port -- riiiiiight?
