Briefly: J.K. Rowling, author of the Harry Potter novels, is expected to make a Potter-related announcement on June 23rd, and it has to do with Pottermore.com. The website just has a “coming soon” page, but it does link to a YouTube countdown to the announcement. There’s also a Twitter account, though none of these give us much hints as to what Rowling is announcing. All we know is that it isn’t another book, and Warner Bros., the studio behind the Potter films, has their name on the site. What do you think the announcement is for?
