This is more a question of growth rate. If you apply the growth rate 
"expected" at the inception of IPv4... and compare that to the 
"expected" growth rate of IPv6... then go extrapolate to calculate 
"actual"...

well, lets just say 2^128 grows a lot slower than some hockey stick 
patterns I've seen.

Does IPv4 space become the "swamp" of IPv6 world then?
