"Price difference between IPv4 and IPv6 is exactly two times."
I don't buy your logic. If IPv6 traffic right now is <1 % of the total traffic and probably won't grow very rapidly any time soon, why does it matter that this year's router model is half as slow forwarding IPv6 packets?

If you enable IPv6 you reduce not only number of packets you can process. You reduce number of routes you can process, etc. And about <1%... this is red herring: if the IPv6 traffic is <1% and you expect to have at on this point for a long time - then why bother (do you really expect significant revenuy from this <1% traffic?), but if you expect that this proportion will grow then IPv6 support means real money. The best alternative is to prepare contingency plans and wait till they will be needed - and this is exactly whay most ISPs are doing.
