More 'Harry Potter' books on the horizon?

'I could definitely write an eighth, ninth, 10th,' Rowling says

"Harry Potter and the Deathly Hallows" may not be the final chapter in the popular boy wizard book series.

"I could definitely write an eighth, ninth, 10th [book]," author J.K. Rowling tells Oprah Winfrey in an interview airing Friday.

For now, Rowling is content with leaving the characters for now.

"I'm not going to say I won't. I don't think I will ... I feel I am done, but you never know," the British author added, saying that she is "in a new phase."

Rowling, who has sold more than 400 million copies of her novels, also admitted that finishing "Deathly Hallows" was "a bereavement."

The first "Deathly Hallows" film is set for a Nov. 19 release, while the second part will be in theaters the following year on July 15.
