Voldemort's death CHANGED in Harry Potter and the Deathly Hallows Part 2?

It's better for people that haven't read the book to show exactly why they're fighting. I didn't like how voldermort died in the book... but scenes from the trailers (jumping off a balcony) seem absolutely ridiculous. I don't see how they're gonna pull that off. But we'll see on july 15th :D
