TechPowerUp found an updated AMD roadmap for 2012, you can check it out over here. The chart reveals AMD's FX-x300 "Vishera" family, as well as the A10 APU series.
Codenamed "Vishera", AMD's new FX-x300 family (where x = 8 in case of eight-core, 6 in case of six-core, and 4, in case of quad-core), will likely be built on the same AM3+ platform, but based on the "Piledriver" core architecture, which brings in about 15% IPC increase over Bulldozer. The roadmap slide talks about FX-8350 being the top-end part, followed by FX-8320, FX-6300, and FX-4320. Around that time, AMD will replace its A6 and A4 "Llano" parts with new A6 and A4 "Trinity" ones. The A6-5400 APU features Radeon HD 7540D graphics, while the A4-5300 features Radeon HD 7480D.
