The DVD and Blu-ray of Harry Potter and the Half Blood Prince is released in shops today in time for christmas. It contains exclusive behind the scenes footage from the set of the next Harry Potter film, Harry Potter and the Deathly Hallows, followed by a 50 second teaser trailer below, and you can watch it below.

Harry Potter and the Deathly Hallows is the 7th and final film in the series, directed by David Yates who also directed the last two Potter films. It will be split into two parts, with the first coming out here in the UK in November 2010 and the second part in July 2011, so theres still quite a wait till the saga will finally be finished.
