They predict that the top countries in the medal count will be:
1) United States
2) China
3) Russia (even without Track & Field)
4) Great Britain
But the really interesting part for me was their predictions for the contributions of female athletes in the overall numbers:
Additionally, Gracenote's analysis has found that women's events in Rio will account for an all-time high of 44% of total medals. Men's events will account for 53% of medals while mixed and open events will account for the remaining 3% of medals. Prior to the 1988 Seoul Olympics, women had won fewer than 30% of all medals. However, women athletes representing individual countries have made a significant impact on the medal counts over more recent years. Japan and Romania (2000 Sydney Olympics), Poland (2004 Athens Olympics) and Jamaica (2008 Beijing Olympics) have had 70% or more of their total medals won by women. The Netherlands currently holds the record for highest percentage of Olympic medals won by women athletes at 85%. The breakdown for the 2016 Rio Olympics are below.
They also predict:
75% of Canada's total medals will be won by women.
59% of U.S.A.'s total medals are predicted to be taken home by women.
Out of 26 total medals the Netherlands is predicted to win, 54% will go to women athletes.
New Zealand and China women athletes will claim 56% and 54% of their respective country's total medal counts.
Exactly half of Brazil's 20 medals will be awarded to women.
Other countries taking home significant percentages of medals by women athletes are Russia (49%), Japan (47%) and Australia (45%).
