The new trailer for 'Harry Potter and the Deathly Hallows' is out. The film will be the final in the series of 'Harry Potter' films and although fans may feel torn over saying goodbye to the wizarding world, author J.K. Rowling piqued the interest of many when she mentioned a secret new project that she's working on.

Rowling launched the website Pottermore, which excited fans this week. Speculation of a new book is being squashed; as Rowling has said numerous times that the seventh book in the series, 'Deathly Hallows,' was the final book in the 'Potter' series. Scholastic told Entertainment Weekly that the announcement is not about a new book. 

Some believe 'Pottermore' will launch the 'Harry Potter' e-books. Others believe it might be a new movie, though there is no evidence that a new film is in the works. Those who have read the book know how the series ends, and while there will be no spoilers here, we can say that many fans have wanted to see what happens ten years from now. 

It has also been speculated that 'Pottermore' is an online video game, which seems likely and probable.
