However, he also suggested that he is involved as a core staff in the game’s development, stating, "As a hint, one thing I can say is that the FFVII technical PS3 demo was supervised by me, and created by Toriyama and his team staff. I'll leave it to you, but you can imagine that development [of the PS3 FF] is happening via a similar process." Motomu Toriyama was one of the directors that worked with Kitase on Final Fantasy X, and the main director for Final Fantasy X-2.
Kitase also revealed the Final Fantasy VII technical PS3 demo was actually a rush job, created in just a month and a half. “We created right before E3. I didn’t think we could do it at first, but I called Sugimoto (Koji Sugimoto, FFX’s main programmer), and we somehow made it. I believe that if we had more time, we could have made it in a higher quality. In that sense, that demo didn’t really take much advantage of the PS3’s hardware specs. But still, we were able to make something that looked that good.â€
When asked if there were any more Final Fantasy VII spin-offs planned in the future, Kitase laughed, commenting, “Well, we’ll have to see. There are still characters that might be alive [From the original FFVII]â€.
