What is amazing to me is how surprising Thuban seems to be. Thuban was pretty low-key, and I don't think anybody actually expected Thuban to be anything more than just "Deneb with two more cores tacked on". Bulldozer was what everyone was waiting for from AMD, but it seems AMD had enough time to improve Deneb significantly before becoming Thuban. Take into contrast what was a few months ago (Nov-Dec 2009) the expectation that the clockspeeds most likely will be 2.6 or 2.8 or similarly not spectacular and not even a hint of "turbo", with what has been leaked and shared so far. It's not an i7 crusher, but perhaps even the staunchest of AMD critics would at least readily admit that Thuban is (or until it is official, seems) a significant improvement over Deneb.
