Although most Final Fantasy games offer new worlds and characters, some things are always in there and Chocobos is one of the things. The giant chickens will of course also be in Final Fantasy XIII as you can see below. There are also some shots of the menus and battles in this latest batch of Final Fantasy XIII screens.
Final Fantasy XIII will be released on Playstation 3 and Xbox 360 on March 9 next year in Europe and North America.
