I find it hard to believe that everyone there is a professional. No hobbyist shooters, schmucks with iPhones, Canon SX50's? Who was the guy that took the shot at the last Olympics of all the photographers pointed toward the sports action? We need a shot from "THAT GUY"!
Yes, you are right. Also with the 1000's of people in those stands I am sure there a few of "us" that are interested in the 7d2. Personally if I were there I would make an attempt to get as close as I could to the photogs to see what I could see.
