J.K. Rowling’s Pottermore today promised that the first three chapters of Harry Potter and the Prisoner of Azkaban are coming “very soon.”

The following tea leaves graphic was posted on the Pottermore Insider this morning:

“The teacups show the shapes of three different creatures – a Hippogriff, a large dog and a rat,” Pottermore writes. “Each creature represents a different Moment from the first chapters of Harry Potter and the Prisoner of Azkaban”

In addition, by visiting the Pottermore Insider you can vote to choose which of the three Moments you get a sneak peek at in advance of the opening: Large dog – “Magnolia Crescent,” “Rat – The Magical Menagerie,” or “Hippogriff – Hagrid’s First Lesson.”

Pottermore opened the last chapters of Chamber of Secrets on October 31, and fans have been waiting for the third book in J.K. Rowling’s series to get underway since then. We expect mini games and new writing from Rowling to be included.

The website this year released Chamber of Secrets in batches in order to get people to make repeated visits to the site throughout the year. Pottermore has also teased that they’re developing new features and ways to experience Pottermore which may open in 2013.

We’ll be sure to offer a break down of Prisoner of Azkaban when it opens. We’d imagine it could open before the Christmas Holiday.
