More footage of the tail shot, note Godzilla's spines behind the building to the left.
Bus spines.
More footage to the flare shot, shows Godzilla's chest armor clearing up that what look like his gills are the serrated plates on the underside of his neck, pretty cool.
I loved that trailer and you know that the jet fighters that fired the missiles at Godzilla on the bridge are so dead unlike the '98 outing. My best part was at the 18 second mark.
