A conservative estimate of the number of SNPs with >5% prevalence in the human genome is 10-50 million. Your observations are consistent with this:

If you go for lower prevalence, you get higher numbers. There was one suggestion passed around in a HapMap course I attended that if you sequenced the entire human population, practically every base would be a SNP (if a single observation would be good enough for validation).
