Single core performance is going to become less important over time as applications become more multithreaded. I am on the server side, I don't deal with client systems or applications at all. For my customers single threaded performance is far less important because all of the apps are multi-threaded.

The proper server metric is throughput, which is a measure of all cores, not the clock speed of one core.

Customers that care about single threaded performance in servers would be staying with dual cores becuase those have the highest clocks. But we see customers abandoning duals in the server world like crazy.

Bulldozer will have more cores than magny cours, but the increase in performance between the two will be higher than the percentage increase in cores, so, to answer in a roundabout way, the cores will be faster, not slower.
That's true, and from a server point of view that's perfectly acceptable. However, increases in single thread perfomance, that means increase of each core perfomance, will have a direct impact in throughput. Also the Bulldozer architecture is going to be in desktop and mobile too, where single thread perfomance is still much more important than multithreaded and I can't see that changing in a long time. If BD cores are not "significantly" faster than Shangai I can't see AMD changing today's situation, where the competition is faster in almost all levels, including the server space, where they're attacking you with less expensive (for them), better perf/watt, better absolute perfomance parts.
