TechPowerUp found a couple of slides that detail AMD's chipset plans until mid-2011. The charts reveal several new chipsets like the 980G, 990FX, 990X, 970 northbridges and the SB950 and SB920 southbridges.
"AMD's upcoming "Bulldozer" architecture based processors that use a new socket type, the AM3+, are slated for Q2, 2011. To complement its launch, AMD will be launching the 9-series chipset series, consisting of four kinds of desktop chipset. The lineup starts with the AMD 990FX, the high-end 4-way CrossFireX-ready chipset, geared for high-end motherboards. Next up, is the 990X. This discrete graphics chipset is also ready for CrossFireX, but has just 16 PCI-Express 2.0 lanes to spare for graphics, platforms based on this will feature two PCI-Express x16 slots which reconfigure to electrical x8 slots when both are populated."
