World Soccer Parity?

There have been several major upsets in the World Cup, which makes it more interesting to watch the games. Team USA ties England. Mexico beats France. Spain loses to Switzerland. Paraguay ties Italy. And this is only after a week of play. In past World Cups, it seems a hand-full of powerhouse teams (Brazil, Spain, Italy, France, Germany, Argentina) could always be counted on to win. Maybe this means that the level of soccer has become stronger around the world, giving more countries a chance to win. And that would be a good thing.
