Square Enix president Yoichi Wada explained, "The next term's schedule has been fixed yet. Presently, I cannot say what kind of effect we will experience from moving the Dragon Quest IX launch from March to July. I cannot say there won't be an effect."
According to Japanese news site IT Media, Wada added, "There is a possibility that Dragon Quest IX delay could effect Final Fantasy XIII." Wada, however, did not explain how it could affect the-long-in-development and eagerly awaited FFXIII.
