Now you have deduced the beauty of the scheme. The number of end points does not matter to IPv6 address planning.
Said another way - my factory subnet may have a gazillion(1) little machines on one subnet while my data center boxes may have several subnets. Just count the subnets. Let the traffic/technology drive the use per subnet whilst you TRILL(2) a pretty tune.
Note (1) Gazillion < 2^64
Note (2) Thanks, Radia
