Nope. If ISPs want to continue getting new customers and there are no  
new IPv4 addresses available then either trade them with some other  
party who has them, or they use IPv6.
The last option might be more expensive at first but it will go down  
in price, whereas the cost of the first option is only likely to  
increase.
This will create demand from the ISPs for IPv6 enabled products,  
though perhaps more in the area of application level gateways than in  
others.
Customers won't care if their ISP gives them v6 or v4 as long as they  
get the service.
