For the two PS3 games, the new reveal on Versus XIII is a pretty big one. It's the first time anyone has seen gameplay images of the game. The images themselves are tiny (pictured above), but it is clearly seen (in the larger version) that numerous pictures show off in-game scenes as hinted by the visible HUD and map. As for the Main FFXIII title, the images don't reveal as much. It's interesting to note that a character design from the title's drawing board has been semi-blurred. It is possible that this design may be a new playable character, though that is not certain. If any of this has you interested, check out the larger sized images here and see the fine details.
