English Final Fantasy XIII demo will be brand new, downloadable (if it happens) reports Joystiq. In short, there's no certainty of an English language version of a Final Fantasy XIII demo, but if there is one, it won't be the same as PS3 demo released on the Japanese Blu-Ray release of Final Fantasy VII: Advent Children Complete with Square Enix's Yoshinori Kitase saying: "if we were to provide the demo overseas, it would be a completely new version."
