Issue 1281 of the Japanese magazine Weekly Famitsu included an interview with Tetsuya Nomura in which he talked at length about Final Fantasy XV, sharing some juicy bits of information.
First of all, he specified that a PC version of the game is possible but still undecided. The team and the publisher are waiting to see if there will be a demand to play the game with full detail, because at the moment the game requires very expensive top-of-the-line hardware to run.
The game is developed directly on DirectX 11, so it can be implemented directly into each hardware, losing the concept of lead platforms. It isn’t tailored to one console. Since both consoles now use Blu-Ray, and optimization still hasn’t been done, it’s still too early to say if there’ll be any difference in performance.
(Editor’s Note: I wonder if the Blu-Ray bit is an implicit admission that the lack of Blu-Ray on Xbox 360 did influence the development of Finanl Fantasy XIII as many argued.)
Nomura-san also shared that the team is considering a variety of online features. He thinks that online gameplay is necessary to keep players playing for a long time. PS Vita integration is also possible, alongside smartphones and tablets, but more information about this will be shared at a later time.
At the end of the interview Nomura-san said that he predicts the quality of the game to increase further from what we saw at E3, and we’ll see more at Tokyo Game Show. He promised that, while Japanese development lagged behind during the current generation, he’ll show the world that this won’t be the case with the next.
