There are literally over one hundred people lined up outside of the campus GameStop. Maybe 200. I don't know that Modern Warfare is going to be THAT good.
I remember there were hundreds of nerds lined up outside of a local gamestop. I was too embarrassed to stand in line so I went to get a milkshake. When I came back 15 minutes later the line had shrunk to about 8 people and I got my copy without a pre-order.
