The first of two Final Fantasy XIII games are expected to hit in Japan by the end of 2008 with the onslaught continuing in 2009. The long wait has not stopped a nice deal of artwork to drool over as the wait passes or more information comes around.
The following artwork consists of Final Fantasy XIII and Versus XIII characters, which can be seen below (credit to Ripten for the images)
What is not confirmed though is if this is straight from Square-Enix or some highly advanced Final Fantasy fan with great Photoshop skills. Either way, they are still great to look at.
