I still think that clip was horribly edited to keep stuff from being shown. Here's what I think happens.
- Wolverine lights his cigar.
- Storm runs towards him. They have some sort of dialogue and he thinks it's clear. They then hear a foot stomp and hide for cover behind the car. (This explains why the music suddenly stops when she hits the side of the car with her back)
- They then hear another stomp and see the searchlights from the Sentinel (no, not its eyes....

)
- Wolverine keeps talking and saying the panties in a bunch line, but his mouth is closed when Storm grabs him and they spin as the wrecked car is crushed. (I think something happens before then, and they dubbed the voice over to make it look like its part of the scene)
- Also, it could be possible that they edited out the Sentinel's body so that it's not given away so we'll have to see the movie to see the Sentinel. (I've seen some movies where they've edited out stuff like that to keep it a surprise)
- It also sounds like they dubbed Wolverine's voice and the electronics going haywire over the scene with the X-Men standing there looking. Instead of sounding far away, they sound close up. This makes me believe that we will see Wolverine atop the Sentinel chopping its head off, but they took it out to be left for a surprise.
