That will be a huge disappointment after rumours the fifth instalment of the wizarding adventures might be out in the summer.
All the other Potter books have come out in the summer.
Bloomsbury, which publishes the books, says on its website the ideal release date now will be "early autumn 2002."
'The world is waiting'
He added: "The whole world wants to read this book" - which probably isn't far from the truth.
But there'll be no release date till JK Rowling has finished writing the book.
Bloomsbury will probably want to avoid clashing with the boy
wizard's second film, Harry Potter and the Chamber of Secrets, which opens on 15 November.
