HBP confirmed to 2009.

Warner Bros. has emailed a confirmation of this new release date with the following quotes besides the one made by Alan Horn.

Jeff Robinov, President of Warner Bros. Motion Picture Group, confirmed: “The release date change does not alter the production schedule for this or future Harry Potter films. Post-production on ‘Half-Blood Prince’ was completed on time, and the studio’s release plans for the two-part ‘Harry Potter and the Deathly Hallows’ will not be affected by this change. We know Harry Potter fans are eagerly anticipating seeing the final chapters unfold onscreen. In fact, the good news for them is that the gap will now be shortened between ‘Half-Blood Prince’ and the first part of ‘Harry Potter and the Deathly Hallows.’”

David Heyman, the producer of all the Harry Potter films, offered: “When Jeff Robinov explained the rationale behind moving the release date of ‘Harry Potter and the Half-Blood Prince’ to July 2009, it was immediately apparent that this offered us the potential to reach the widest possible audience. I am extremely proud of this latest film and of the work of David Yates and our incomparable cast; I believe we have developed and pushed the series further still. We are all looking forward to sharing it with Harry Potter fans around the world, even if we have to wait just a bit longer.”

David Yates, the director of both “Harry Potter and the Order of the Phoenix” and “Harry Potter and the Half-Blood Prince” and who will also helm “Harry Potter and the Deathly Hallows,” added, “It has been a joy to work on ‘Harry Potter and the Half-Blood Prince.’ Dan, Rupert and Emma and all our returning young cast continue to blossom, and our new cast members bring fresh color and life to Hogwarts. Even as we put the finishing touches on this latest film, we are already beginning preparations on the final two films—we start filming in February—and I am excited to bring this remarkable series to the exciting and moving conclusion its loyal fans deserve.”
