Instead, they'll just roll out 6RD relays like Qwest/Centurylink did.  You didn't REALLY need a 1480 MTU, did you?

Not true. The Netgear CCB tried to install here just a couple of days ago is IPv6 capable. Unfortunately, it breaks IPv4 by not being capable of bridge mode and insisting on NATing everything inside unless you subscribe to static IPv4 addresses from Comcast.

OTOH, you can supply your own Motorola Surfboard DOCSIS 3 modem and it works just fine with Comcast Business.
