I, for one, would love to see some studies done on the (potential) long-term
effects of soy formula use in children.  As far as I know, no one has done (or
published) such studies.  If it turns out that there are, indeed, significant
long term effects of soy formula in infancy, it would be another good thing to
add to the list of formula risk/breastfeeding benefits.
