I have some mixed feelings. Yes, you have the idea of authority with the "old fashioned" and "classic" layout, but isn't it also too much "WordPress the blogging platform", while we also try to focus on the more advanced CMS possibilities? We already touched on that while discussing the taglinewhile discussing the tagline. We (or at least I) really like advanced solutions to advanced problems, and I somehow don't feel that idea of being "cutting edge" in this design.
Personally I really like the design of WPEngineer, but this is probably too close to the current sketchy theme to be taken as a starting point?
