The Register has a nice article regarding AMD's upcoming processors. The FX-59 which will be clocked at 3GHz is currently planned for the first quarter of next year, along with a 2.6GHz dual-core Athlon X2 (possibly with a 5000+ rating). And the new Socket M2 is slated for Q2 2006.
The first Socket M2 parts will use two cores, 'Windsor' and 'Orleans' - the former is the dual-core version, the latter will be used for single-core products. The new interconnect is all about adding support for DDR 2 memory, which the new chips' integrated memory controller will cater for. They will also support 'Pacifica', AMD's answer to Intel's Virtualisation Technology, and 'Presidio', the chip maker's upcoming security system, which, again, will be pitched against Intel's 'LaGrande' security technology.
