One thing though is if one were in the camp of 8GB being not enough should they not also assign considerable value/progress to 8GB->16GB?
Maybe but some of those same people believe 16GB should've been standard 2 years ago. Ironically the feeling of entitlement for 16GB seems to be suppressing their enthusiasm for 16GB. Part of the skepticism is pricing too. Nobody believes the 16GB card will be available for $429.
