The Gamespot reviewers got their hands on Final Fantasy XIII first hand on PS3 and XBox 360. It is noted that it is extremely hard to tell both versions' graphics apart. This is a soothing news for me since I was afraid that FFXIII on XBox 360 will be as bad as I heard in rumours, as I really anticipate this game very much.
