IPv6 Question (just thinking about the lack of NAT)

I am reading up on IPv6 and trying to be a little ahead of the curve. I am reading that "most" organizations will probably use a dual stack network that supports both ipv4 and v6 for some time.

In my reading I am learning that IPv6 doesn't support NAT and I understand why it isn't needed and I also understand why some (including me) would want NAT but a simple question came to my mind.

Eventually when your ISP switches you over to IPv6 how would a company like Netgear or Linksys make a simple wireless router for use at home. If there is no NAT then each device behind the router will need an IP assigned from the ISP. That doesn't sound like much but it sounds like a great money maker for a company like Comcast or Verizon that would want to charge you for every IP/device you have in your home, Just like a set top box. Just imagine paying $4.99 for every computer/phone/xbox/etc... I did a quick thought and I would be paying well over $200. Just imagine this in the business world with offices that have thousands of devices….

Am I wrong in my thinking or would there be another way?

I realize that this may be some time away but that just doesn't make sense to me....

It's been a long while since I had an intro to v6 but from what I remember, the ISP is only going to need to assign you an portion of your ip, your systems will "auto-negotiate" the last part of the address and so you'd have some insanely high potential number of IPs just for yourself.

The ip is a 128 bit address and the isp would only be assigning the first 64 or 80 to you.  Put another way, with v6 they wouldn't be assigning you an ip address, they'd be assigning you an ip block of addresses.

Ah, thank you guys I see now and that would make sense.

I didn't see that part in my reading and really that was just one of the first things that came popped in my mind.
