Square Enix has announced it will reprint the Final Fantasy VII Ultimania. This book contains information on not only the main game but spins off such as crises core and Advent Children. So it should fill in some blanks but not all of them.
Now this not to be confused with the remake version as they are completely separate. Also keep note that this is a Japan only release. So you will have to ask a friend or make a Japanese account to get this. The Ultimania will go on sale June 18th.
