2. AMD learned more about Prescotts capabilities and concludes 128-bit memory channel is indeed needed for launch already to prevent from any QS-rants after Prescott-launch - unless anything above 2 GHz is achievable.

This is most likely the reason - they have decided to launch A64 with dual memory channels, ie with the same socket as Opteron 14x. Socket 939 could be an attempt to bring back the lost market segmentation between A64 and Opteron motherboards.

Disappointing that they make this decision so late if true.
