I suspect that we would only see a speciation event like this if people with Down's syndrome were segregated from people without Down's syndrome and allowed/forced to form a parallel society. It's hard to imagine modern human society tolerating such an apartheid, leper-colony style of treatment of people with Down's syndrome, however.

Besides there is already a social taboo against engaging in sexual intercourse with them because of the substantial power asymmetry. So really the only impediment to speciation is the lack of fertility.
