Oscorp
If you have remember the first Amazing Spider man trailer you got to see the Oscorp building (see below...)
Now since the new trailer has came out every one knows that there is a climatic scene between the Lizard and Spider-man on top of Oscorp but it has changed.
1. Oscorp has several buildings around New York and Dr.Connors used one of there labs then transformed there.
2. When re shooting in New York they weren't able to use the same building as in the trailer so they used the closest one to the old one
3. It's just a random building the lizard was on during the fight between Spidey
Webshooters or...
In the trailer you see Peter working on his web shooters in his lab
I know they're webshooters but what if they're not if you look at them the y have a radar like pad that has a switch on the side.
This could be the spider tracers that Peter uses to find the Lizard in the final battle
Final Battle
Everyone noticed the final battle but when Spidey swings at Lizard but look behind is this giant pipe of green fluid. Lizards plan could be to spread the Lizard formula around New York.
Peter probably drops it in the sewer which causes this
Then uses spider traces to find him in the sewer and the two have a battle under water.
That is some of the stuff I notice throughout the trailer
Starring Andrew Garfield, Rhys Ifans, Emma Stone, Denis Leary, Sally Field and Martin Sheen, The Amazing Spider-Man is set to hit theatres on July 3rd, 2012.
