They are. I was part of the test rollout of IPv6 when I lived in Richmond, VA last year. It worked flawlessly so I'd assume they should be set for a greater rollout sooner rather than later.
When was that? It's been "coming soon" on Verizon's own FAQ[1] for almost half a decade now. I'm in one of the major MSAs along the eastern megalopolis, and there's no IPv6 here.
