Two Mega Trailers Premiering with Harry Potter?

Word is that two giant movie trailers are going to be attached to Harry Potter and the Deathy Hallows Part 2 when it arrives next weekend.  One for one of this winter's biggest releases and the other for what is arguably next years biggest releases.  What are they?

Are you sure you want to know?

How about Sherlock Holmes: A Game of Shadows?

That's not big enough for you?  Okay.  How about the first teaser trailer (reportedly 93 seconds long) for THE DARK KNIGHT RISES?

More than enough reason to join the rest of the world at the movies next weekend no?
