Ain't gonna happen. They won't be able to go anywhere close to 3.0ghz. They're just revealing 45watt tdp k8's now. They probably wouldn't use those, so the tdp would be a big drawback. Plus- they're not gonna drop money on designing crossbars and ht links into the processors for those ends. And if they did, it would be to admit that k10 quads aren't necessary and intel has the right idea of double-duals for quad, vs phenom integrated quad
::EDIT::
As intel and amd architectures become more similar, we're going to see a ramping of speed in a ghz-wars style again. If shanghai scales well in tdp performance, then amd quads will be able to clock fairly high well. I feel with more bios revisions, driver updates, and bug fixes, we'll see phenom competing fairly well with penryn- AMD just needs to perfect their design and manufacturing process.
Amd will still have an advantage when nehalem comes out- more experience with integrated memory controllers. Which will strike a cord with AMD's largest market- business and server-side customers. They like to see stability and mature platforms more than shiny new promises like enthusiasts chase
