As announced last week, there was a brief preview clip shown for Half-Blood Prince during the 81st annual Academy awards' end credits, as part of a montage of numerous movies to be released in 2009. However, most of the scenes shown throughout the video have already been released in prior trailers, save for a Quidditch sequence between the Gryffindor players (Ginny and Ron). It can be seen below.



Harry Potter and the Half-Blood Prince will be out July 17, 2009.

UPDATE: Screencaps of the new bits can be found here.
