The final trailer has been released for Harry Potter & The Deathly Hallows, Part 2, featuring a ton more footage from the final battle. (A battle that appears to have been extended quite a ways beyond what is depicted in the book.)
Fiendfyre! Lupin & Tonks! Sirius Black?! There’s a lot that seems to have been snuck in to this trailer, as opposed to earlier ones. Enjoy!
