Lets see. There are 13 KSers so far for 2013 and we officially have 2 months left.
There are, in my opinion, only 7 players capable of achieving a KS with a high probability within these 2 months (not going to name names). In addition, 2 of which, possibily even 3 of these 7 dont have a chance in hell because of their chosen pace.
So in my opinion, it is only possible that 4-5 people could physically do it in these last 2 months. Then when you account for the fact the it is even more unlikely that all will achieve a KS in this amount of time we must atleast divide this by half.
So at best 3 more KS's this year for 2013. However, im going to be a glass is half empty kinda person and say there will probably only be 1 more KS this year.
I will go one step further and say that it will most likely be done by Mitchell at this years Kong Off, from years of compiled guilt and yearning
