That's a very reasonable position, especially with Comcast. Comcast has, in fact, led the IPv6 charge in terms of sizable US ISPs. The flip side of that coin is they have the money to invest in the engineering costs. I assume they did some analysis, computed the cost of NAT vs. IPv6, knowing full-well they'd have to do IPv6 sometime, and plowed ahead.
It's the smaller ISPs that are just used to fixing stuff "when its broken" that are really in trouble.

What does surprise me though is that IPv6 hasn't seen steady uptake when new companies set up new infrastructure from scratch or existing companies upgrade their kit. I would have thought that using IPv6 exclusively internally with DNS64/NAT64 to bridge the external IPv4 internet would offer some advantages.
