Modern Warfare 3 trailer - In detail

So it looks like the fellows over at IGN are trying to figure out and pick apart the four very lame trailers for the upcoming super hit; Call of Duty: Modern Warfare 3.  To my surprise it doesn't really explain much, and it's all hype right now.
But for those who care, take a look and enjoy.  Leave a comment telling me and everyone else what you think these trailers mean.
Have fun and enjoy.
