Deathly Hallows trailer debuts at Cinema Expo, to play in front of Eclipse in theaters

UPDATE: We’ve now learned that the trailer will debut online Monday, June 28th at 7 PM ET/4 PM PT!

A couple months ago we briefly reported that Warner Brothers would kick off their Harry Potter and the Deathly Hallows marketing campaign starting at the end of June.

This information has once again been confirmed by an entertainment and media analyst who caught the trailer at Cinema Expo International in the Netherlands earlier today.  

Moreover, he says the Deathly Hallows trailer is the best trailer of the year and contains footage from Parts 1 and 2:

New Harry Potter teaser will play with Twilight’s #Eclipse next week and includes footage of both part I & II. Best trailer of year so far! Based on the FANTASTIC teaser at CinemaExpo, Harry Potter and the Deathly Hallows, 2D looks amazing in itself– no need for 3D

We have heard rumors that the trailer may debut online as early as June 28th. However, this is NOT official yet. At the least, you can expect to see the trailer with The Twilight Saga: Eclipse in theaters on June 30th!  Thanks to Sue for the tip.
