Half-Blood Prince Teaser Trailer with Dark Knight?

Anticipation has been high for the Half-Blood Prince teaser trailer, which is long overdue in comparison to the Goblet of Fire and Order of the Phoenix releases.

According to our latest poll, 50% of you believe that the trailer will be released with WB's The Dark Knight. That now looks more likely than ever, with this tip coming in from MuggleNet reader Taylor:

I work at a movie theatre in San Francisco and we recently received our official word on print delivery for our IMAX print of Dark Knight. In the e-mail giving us the date of arrival they added that we could expect our Half Blood Prince trailer for that print to arrive two days after- over a week prior to the 12:01 a.m. release of Dark Knight!! Yay!!

Please consider this a rumor until Warner Brothers gives us official word. We'll keep you updated!
