Harry Potter publisher, Bloomsbury, claims the final installation in the series should be out in 2007.

The statement comes from the company's Director of Publishing, Liz Calder, who made the prediction whilst on a visit to India.

At the British Council’s Creative Future conference, Calder reportedly spoke about J.K. Rowling's future, as well as the ever-popular novels: "One more Harry Potter only but she (Rowling) said from the beginning that she would write seven. So she would not write another one after this. But Rowling would write other books for us."

”The next Harry Potter book is likely to come out in 2007. I hope so.”
