Speaking at the aforementioned Japan Expo, Tetsuya Nomura offered a few details regarding Final Fantasy XV. Apparently, the outfits were actually created by a third party: a Japanese fashion company named Roen. Roen went through the effort of making physical copies of the outfits, which the CG team has been recreating in the game itself.
Back when it was known as Versus XIII, the game would end when Noctis died; this element may not be present in the final version, according to Nomura. Dual audio is also in question, as it “all depends on the capacity of the disk.” He did, however, confirm that vehicles will be used throughout the game, ranging from a simple car to Magitek armor.
