Who doesn't survive?

I know that people have read rumors and had discussions about which bot gets slagged, but what I really want to know is what human dies. In the 2 min trailer you see Sam saying to Prime, "This isn't my war." (:49 in). He's dress all in black and they are in a cemetery. So who gets killed? His mom? Dad? Since he's not all jacked-up it's probably a good guess that this happens earlier in the film. I took a screen shot, but for some reason it won't attach.
