Now my personal opinion on this is whilst it looks like Naruto dies, I doubt that he does. It isn't even wishful thinking, after seeing that ad I am worried that my favourite blond dobe is going to be killed (if he is I bet it is that white haired bitch's fault...grrrrr...I dislike her already!) but some things point to that not happening...first of all I know that there is a lot more of Shippuden left that they haven't made into anime, secondly look at the subtitles, it says in there that 'this is the start of a new story' now unless they are going to follow some other ninja (in which they would have to retitle the series seeing as how the main character is dead!!!) which I feel is highly unlikely. Plus Tsunade looks at peace not pissed off when she is staring out over Konoha, if Naruto truly was dead then she would be going mad! I mean we all saw what she was like the last time she thought Naruto was in danger! No. What I think happens is that Naruto has to leave Konoha for some reason so Tsunade says he is dead or something to that effect. And yes I do see him getting stabbed in that ad but I mean come on Naruto! The vessel of the Kyuubi...we all know that normal wounds that could kill a person are nothing for him to heal! If he does come close to dying then I am pretty sure that the white haired girl will play an important role in stopping it from happening...and that bell has something to do with it I reckon.
Well there is my guesses for the movie, I guess I'll either have to wait until the movie comes out or until another trailer comes along.
(I really hope poor Naruto doesn't die...he's really grown on me! I can't imagine what my days would be like without the excitement of waiting for the next installment of his story...plus he still has to become Hokage!)
