   Educated guess:   
      
   Comcast follows the example of the European daughters of Liberty Global:   
      
   New customers or customers that for some reason get a new modem/router are put   
   on a DS-Lite connection. On request they are downgraded to an IPv4 only   
   connection. Dual Stack is phased out and only available on high end bussiness   
   accounts.

   Here in The Netherlands the DSL and fiber providers that offer IPv6 still   
   offer Dial Stack. The cable companies are going DS-Lite.
