Warner Brothers Mexico has confirmed to Blog Hogwarts that the official trailer for Harry Potter and the Half-Blood Prince will be released with Mummy 3 on August 1st, which is just 2 weeks after we get the 15 second teaser with The Dark Knight.

On a side note, Mugglenet has gotten a transcript for the 15 second teaser:

A black screen with Dumbledore saying "Once again I must ask you to do the impossible, Harry." After that, the film title is displayed along with the release date...and that is it.
