Square Enix has said that their current plans for FF and KH series is to release games on any platform that supports DX11, seeing as PC does and obviously has for a long time. It's a very likely course that they'll bring it to the PC as well. I'll still play on the PS4, I like those sorts of games on my TV rather than PC monitor.

They had a number of mistakes in their survey though, most of their other selections weren't actually selectable. Which was a little annoying since I actually needed other most of the time.

I assume it's the English branch doing this and then probably sending it back to the main branch in Japan. It's going to be funny when they see who I put down for your current favorite band or musician and I put down someone that hasn't been relevant for nearly a decade. They'll be like we asked for your current and I'm like "yup" it's my current. ^^ I trust them to know who they are, though it'll be funny if the English arm is clueless about who was popular in Japan.
