CG NAT breaks console multi player for most games (those without dedicated hosting) it will break voip systems such as skype and sip. it will break in game voice comms.
Guess what has no IPv6 support? Xbox, PS3, and Skype.
I will point out, though, that Dual Stack Lite may end up being cheaper for ISPs than NAT444 because CGNs are relatively expensive and native IPv6 traffic (including Google and Netflix) doesn't have to go through a CGN.
I actually have none of these; ... I bet all of these will work over CG-NAT.
Yes. Let's gamble the indefinite future health of the internet on what works for you, a single point of reference, right now, at the very beginning of the IPv4 shortage, without a single thought spared for use-cases not concerning you.
That sounds like a very good and not at all short-sighted strategy.
That's not what I intended; I don't know what the issues are with any of these w.r.t. CG-NAT, since I don't have or use any of them. It was a request for clarification (you know the part of my quote you turned into ellipses).
I do know that every place I have been to the PS3/Xbox has been behind local NAT, so I would be surprised if CG-NAT broke these; my understanding also is that both of them have a central service for game-discovery which means there is no reason they couldn't implement NAT traversal there.
I also never said that CG-NAT wasn't more short-sighted than ipv6; rather that the ISPs have no motivation to deploy ipv6 and much motivation to deploy CG-NAT.
