There is nothing to indicate that ISPs are going to change their business
models simply because IPv6 address space is plentiful; they charge extra for
two hosts because it is assumed two hosts consume more bits than one, not
because a second IPv4 address is hard to come by.
There is nothing to indicate that they won't change either.
ISP will meet their customers expectations or they will go
out of business. Today you expect to get a single IP address.
If you make the expectation be that you will get a prefix ISP
that fail to do this will go the way of the dodo.
The cable provider I'm using didn't allow home networks at
one time (they also had a single flat fee). They do now
though they leave the implementation and support to you
(multiple volume based plans). Customers expect to be able
to connect their home network and the expectation is now
being met.
