You know what hopefully never comes to fruition as an unfortunate truth.
If (when) Greco gets added as a Women's sport at the Olympics it will likely cause them to reduce weight classes again.
Right now they offer 18 Gold, 18 Silver, and 36 Bronze.
That number goes to 24, 24, and 48 respectively if they keep the same weights.
I don't see the IOC doing that.
If we are lucky they will go to five weights, or 20/20/40.
A more realistic guess would say they go to four Olympic weights (16/16/32).
