What will the new Harry Potter site be? It's not about J.K. Rowling's new book, neither is it about the final Potter movie, 'Harry Potter and the Deathly Hallows: Part 2' that releases in July.

Fans speculate that the website could be an encyclopedia on Harry Potter.

I sincerely hope Pottermore is the encyclopedia Rowling said she'd make, a Harry Potter fan in Olympia wrote on his Twitter update.

Will it be an announcement about a new book or the release of an already written new Harry Potter book? Harry Potter fans were disappointed when Rowling said she was finished writing Harry Potter books in 2007. The last and the seventh book of the series came out in the same year.

I hope that one day when I click on #pottermore there'll be a note from J.K. Rowling saying 'I am writing another book'. That would be amazing, another fan, Sarah Beth from Alabama, said.

Harry Potter fan site Leaky Cauldron revealed that according to the trademark information of Pottermore, which was registered in 2009, the site is trademarked for, among other things, multiple-user networks, online boards, digital audio, printed books, toys, retail stores, and more.

The Harry Potter “coming soon” website features just the site’s name, the author’s signature and two watchful owls on either side giving the wholesome “wizard” effect.

So hold your breath, wait till June 23 when the mystery unravels.
