I am sure it will be new areas, weapons, monsters, armor...etc...you know the basic stuff which is included as DLC in games.
I want to see all of that but maybe they will include things which change how the game itself is played...like the International Zodiac System changes for FF XII.
Maybe even a limited online multiplayer system like in Fable II where you can trade items and money or even jump into someone else's FF XIII game and party up.
I would also like to see the ability to continue playing the game after it is done, I.E keep doing quests or monster hunts...after the final battle.
