I recently posted this at Tom Felton Daily.
Warner Bros. Mexico has confirmed to Blog Hogwarts that the official teaser trailer for Half-Blood Prince will be released on August 1, 2008, when it will be attached to the forthcoming The Mummy: Tomb of The Dragon Emperor.
We are currently unaware of the online release date for the trailer, and will update with more information about the teaser when we receive information.
Harry Potter and the Half-Blood Prince hits theatres November 21, 2008.
Please Note: This is not the 15 second trailer/soundclip that has been relased with “The Dark Knight” in IMAX theatres. This is a real theatrical teaser trailer. About 1 minute or so long of footage.
I’ve also posted a new HI-RES Draco promo from OotP. You can view it *HERE* =)
