Of course, this is just a rumour at this point, so take it with a grain of salt. According to 3Dcenter.org, the new names are indeed legit and they include three GPUs, Bermuna, Fiji and Treasure Island. All three appear to be 20nm parts, which means they’re not coming anytime soon.
As for Volcanic Islands, the codenames are New Zealand (again), Hawaii, Maui, Iceland and Tonga. They should appear in late 2013, but details are still sketchy. Let's just hope they're more Captain Sparrow than Capitan Morgan.
TSMC’s 20nm node won’t be ready for mass production as soon as GPU makers would like, hence it should take at least six months before we see the first 20nm Radeons and Geforces.
