Socket M2, the 940 pin DDR2-ready Athlon 64 Socket, will launch a little bit later than we originally expected with mass production just starting in late April. However, even though the launch has been slightly delayed from the original March timeframe, there is still good news for those on DDR1; Socket 939 will stick around well into Q1'07 on the performance desktop - and well beyond that for Sempron. In fact, AMD's latest roadmap goes all the way to Q2'07 with Socket 939 Sempron.
