Probably just a new stepping in the Piledriver for the future. Will not see a new FX till they release a non APU (no GPU with L3) Steamroller for servers. My guess the desktop version will be the same socket as the APU at the time. Really though, I don't think AMD will ever release a new, what we see as a FX. They might go cheap and start calling the disabled GPU APU, like the now called Athlon 760K. Just change the name from Athlon to FX.
