I'm a little bit bothered that ISP professionals in 2012 seem to 
seriously believe that an IPv6 deployment involves disabling IPv4.

How widespread is this misbelief?

I'd fully expect that legacy IPv4 will stick around for the 
forseeable future.  It'll suck, and be heavily multi-NATted, and
fewer and fewer people will use it;  But it isn't going away for
quite a while.
