I might be wrong but I think the 2007 film is the only one that didn't spoil any deaths in TV spots or trailers before release. I know I might be wrong since 2007 was a long time ago.

 

Haha... wow... "It's the Transformers we've been waiting for!"

I know every single review has already been saying it, but now they're putting it right in the official promos too. I'm sure Bay won't take that personally or anything  

 

I want to know why this is a thing, especially with transformers movies. It’s so completely unnecessary, like the editors think “Heh, let’s spoil the movie for people.” TV spots don’t even need many extra scenes either. Just reuse all the trailer shots.

 

It's only spoiled if she does die there.  

One can only assume, unless you've been told....
