With all of the early upsets, it's more clear to me that soccer is likely approaching basketball in that there is more and more parity among national teams as time goes on. World soccer used to be dominated by basically a few nations from just two continents, but that may soon cease to be true.
As with basketball, as the popularity of it has spread, there are now far more competitive national sides from just about every continent, and even some of the former also-rans from Europe and South America can pull upsets against the traditional powers from those continents. More parity is an inevitable outcome of the growth of any sport worldwide.
