I hope you are right
@Mr. Ite about the model/scene swap.
The way the current trailer is cut, it looks like team CAT are scared of entering the ghostly train graveyard on their trek to the Sector 7 slums. While I like the enhanced spooks of the train graveyard and I wouldn't mind the party reacting a little bit to the spookiness of it all, the context of urgency that is supposed to be present (team CAT wanting to stop Shinra's plan to drop the plate) would make this Scooby Doo-esque scene feel very inappropriate. There's no time to hesitate and grab Cloud's arms, dangnabbit.
Then again, the story may have been changed so much that the segment in the train graveyard is
supposed to be without a sense of urgency. *shrugs*
