No rational commercial Internet organization is going to block themselves off from that customer base.  Folks like Comcast will probably add IPv6 support _in addition to_ IPv4.  Eventually, they may even add a surcharge to encourage people to migrate off IPv4, but I'd imagine that's way down the line.  By way of analogy, how long did pulse dialing continue to be supported in the phone system after DTMF was introduced?

Actually, I suspect that once orgs. like Comcast have IPv6 fully deployed you will very likely see increasing fees for "Legacy IPv4 Support" from those providers.  Once that happens, there will be eye-ball consumer pressure for content providers to be available on IPv6 or lose business.

Pulse dialing is still supported in most PSTN switches.  How often do you think it is still used?

Frankly, the biggest reason Pulse dialing wasn't deprecated faster was the number of Telcos that charged extra for DTMF support for so long. Once the DTMF surcharges were removed, most users converted almost over night.
