ISP's are very good at one thing, driving out unnecessary cost.
Running dual stack increases cost.  While I'm not sure about the 5
year part, I'm sure ISP's will move to disable IPv4 support as soon
as the market will let them as a cost saving measure.  Runing for
"decades" dual stacked does not make a lot of economic sense for
all involved.
