Rowling did not announce the publication date of the Harry Potter Encyclopedia. Although the Harry Potter series had been translated into many languages and received a wide range of readers and awards worldwide, the publication of the Harry Potter Encyclopedia was still unknown. Some speculations suggest that the Encyclopedia might be launched soon after Rowling's next novel, The Sorcerer's Stone, or a few years after Harry Potter and the Deathly Hallows. However, these were just guesses. There was no conclusive evidence to indicate when the encyclopedia would be published.
