As first spotted on Reddit, an Amazon UK listing for the official Hogwarts Legacy art book changed its release date from what was previously a generic end-of-year placeholder.
The page now states that the book will be released on December 6, 2022.
Amazon listings are by no means any sort of confirmation, but there are arguments to be made for its legitimacy.
This particular book might simply release before the actual game does or the date is simply an internally slated date that could very well be pushed back.
