HBP mix: No trailer with Prince Caspian, new pic of Harry?

For the past few weeks now, rumors have been circulating around the web that the Half-Blood Prince teaser trailer would be released with Prince Caspian tomorrow. Warner Brothers never passed official word along, and today MuggleNet visitor Christine informed us that the Prince Caspian reel delivered to a movie theater she works for definitely does not include the trailer. Additionally, this new picture of Harry was sent in by Potterish and Oclumencia, likely from Half-Blood Prince (what Harry is wearing can be compared to this picture). It depicts Harry looking into some sort of drawer. Any ideas? Leave 'em in the comments! Thanks again to Christine, Potterish, and Oclumencia!
