Does anyone know......

On the link for The Twilight Saga: The Official Guide (Hardcover) it's stated that; "The publisher of Stephenie Meyer's The Twilight Saga: The Official Guide has not yet announced a release petsa for this title." But it also say that they will update with details as soon as it's made available to them... So it's hard to say when it will be released in Australia, but at least I think it's available for pre-order from link.
