Will we ever see another Triple Crown Winner?

[Holland Hacker]

I have been wondering about this for a while now and last night I finally had a chance to summarize some data. Based on some quick information taken from Champions it appears that a Triple Crown winner has faced approximatley 10 horses less than those that have won only two legs of the Triple Crown. For the winners of 2 legs I started with 1981. Please let me know if I left anyone out.
