There's an interview with Hajime Tabata in the latest Weekly Famitsu (which came to our attention via Gematsu) where the Final Fantasy XV director offers his thoughts on a possible PC port of the game, and upcoming VR content.
"I'd like to release the game on PC as a technical attempt. I want to show PC users Final Fantasy XV running on high-end machines, and we personally would like to see it, too. Also, I would like to try developing on PC to pursue a unique way of playing with PC-exclusive features like making your own quests and enjoying the world using things like mods."
In terms of the virtual reality coming for the game, Tabata added: "Development is progressing, but we haven't progressed to the point where we can say specifically when it will be released."
