If you attend next week's IETF in Sweden, you will see quite a number of 
Cisco employees involved in nearly every aspect of IPv6, including 
transition technologies.  We are there because we continue to believe 
that there is no Plan B(*), that IPv6 is the best way for the Internet 
to grow.  We are also there because many of our service provider 
customers are in agreement.  What we all seem to recognize is that there 
is a challenging transition period coming, and that it will have to be 
carefully managed by vendors, service providers, and large enterprises.

(*) One could argue that we are still cooking Plan A.  For those who 
attend IETF, there is a draft, for instance, that looks at improving 
both TCP and DNS timers to ease transition.  This builds on work that 
Stuart Cheshire presented some time ago.
