Truthfully, using the standard international medal counting method of gold medals, USA will lose out a lot to China.
USA have half of their medals from swimming (so freaking boring watching one guy phelps winning nearly half of their medals) while China has won from such a wide variety of events: gymnastics, diving, weightlifting, judo, shooting, fencing, etc.
Also in the events coming up, though USA has track and field, even then it is heavily contested by other nations such as Russia, Jamaica, and the african countries.
You people have no idea that China's strong events are not even half way through yet, they still got gymnastics, diving, table tennis, badminton, rowing, taekwondo, heck even boxing they have seven athletes doing well in it.
Honestly, China has a whole lot more variety than the USA and I think USA will take a licking this time.
BTW, regarding the women gymnast age issue, don't even mention it, it's bad enough that we lost, if we insist that we lost to so called "underage" girls, it's even more embarrassing and show that we are whiny losers. When we lose, at least we lose in style.
