Ironically it will probably be the more tech savy (the more luddite ones anyway) to be the last people on IPv4 only as everyday people's cable modems and router will have IPv6 enabled by default it looks like. I know I am sure to disable IPv6 everywhere I can (computer, router, etc) because #1 my ISP still gives me IPv4 only and #2 I don't want to worry about the twice the attack surface and twice the firewall rules and tc settings at home.
