amd did say that they would support dd3 in their dual cores by 2007 some time last year. Their were also recent that the m2 socket would be skipping ddr2 and moving to ddr3, pci express2 and wimax.
This would have been a good move for amd, holding off untill ddr3 makes good business sence and would allow them to bring itto market before intel. Butit seems as though they have choosen to bring in ddr2 afterall, hoping to phase it in the august time of this year for the 939 skt.
