USA will win overall medals (they have 102 currently, 13 ahead of China's 89).

China will win the gold medal chase (they have an impressive 47 currently (47 gold and 17 silver, tell me judging hasn't skewered those numbers out of proportion).

Russia probably will finish third in total medals (they're at 57 currently).

The interesting race this final weekend is who finishes third in the gold race - currently Great Britain has a precarious 1 gold medal lead on Russia (18 to 17) with Germany four back at 14.

Another interesting race will be between Great Britain and Australia to finish fourth in the overall medal race (GB has 44 and Australia has 42). Personally I think it's going to be tough for Australia to catch the Brits).

There are 44 events left to award medal - 11 in boxing, 8 in athletics, 6 in canoe and then assorted other sports.
