They can't ramp the clocks up higher on the mainstream stuff yet too, because it would be performing better then the FX series, Which would blow the whole point to even buying an FX. Look what happened with ATi and the R520, they released new tech with higher clock speeds on an unproven process, and they got tons of problems that needed to be worked out before they could even launch it. Even Intel did these kind of tactics. When they moved to the 65nm Presler core. Those parts weren't clocked any higher then Prescott, and no one doubted that they didn't clock higher then 90nm Prescott. Intel was testing out 65nm before they put C2D on full production. Simple as that. Also when Intel was going to the Presler core, NO ONE doubted that they could clock higher then the 90nm Prescott, but with AMD, tons of people believe 65nm is clocking WORSE then 90nm, even though Intel did the same thing with the same launch clocks.
EDIT:
@accord, yes it would have helped the launch, but 65nm is still an unproven process, If AMD sent out 65nm FX parts with defects, imagine what that would have done to the launch.
