The guide is being published by BradyGames, the guide is updated to cover the International features in both games that were never available in North America before – such as the Dark Aeons in Final Fantasy X and the Monster Create system in Final Fantasy X-2. It also contains a full story walkthrough for both games, as well as full coverage on all side-quests and mini-games.
You can pre-order the strategy guide from Amazon now for around $18 (at the time of this posting).
