Before IPv6 is taken for granted, the routers have to be upgraded to support it, as will all the ISP addressing schemes. Of course, many ISPs will choose to stick with IPv4 addresses internally and start dealing with IPv6 outside of their realm, slowly integrating IPv6 into their systems. After that, we go to the LANs, and the final frontier is the home network. It's possible that some steps may happen at once if big enough pushes are made. If every cellphone on Earth suddenly has Web capability and needs an IP address when G3 technology is rolled out, perhaps this will push IPv6 faster.
Cisco remains a pioneer in networking.
Just as it is releasing 10-Gbit Ethernet devices before the standard is hashed out, IPv6 is another point where it can gain or retain marketshare by having the newest technology. Maybe that's one thing we can be thankful for. The first comment doesn't count. Acutally, this is what the addresses look like. They are represented in hex instead of dotted decimal notation.
