Before you freak out in a whirwind of fan emotion, be mindful that this isn't confirmed, although the likelihood is indeed Quite High - which in itself is exciting enough.
ComicBookMovie are reporting, via some cinema-based sources, that the second part of Harry Potter & The Deathly Hallows will come with a teaser for The Dark Knight Rises when it's released on July 15th. This is totally plausible - there was a trailer for The Dark Knight in July 2007, although the one thing that was missing was actual footage. By July the movie will have been in production for at least two months so maybe we will actually get to see something this time! If not, I'm sure a growl from Bane or purr from Hathwoman will more than suffice.
