Yes.

I used to think that this would take 10 years, but now I believe 
that it could happen faster because the transition from IPv4
to IPv6 is so much easier than IPX or DECNET to IP.

I also believe this although it doesn't matter for the Internet 
anymore than all those devices currently working through I2C or RS232
to Ethernet proxies.

In a datacenter I expect that folks are already deploying
IPv6-only servers. But then datacenters already hide behind
a forest of load-balancers, caching proxies and so on.

One size does not fit all.
