Awsome trailer, I also found a vid of this on youtube of it playing on times square in NY xD
Though some small things I noticed:
at 0:31 - Ipod touch right side of the image
at 0:38 - Statue of liberty (on the news paper), could be interesting...
at 1:04 - Face looks an awfull lot like a korean guy from Crysis 1. Working together?
at 1:34 - Clearly alien fighter troops
New york seems to be ground zero? City completly evacuated. Other large cities also have the same problems?
Or is it just New York that is under attack?
