"After discussing the design with Intel though, we found out that like Dunnington, Gulftown will feature a similar design as Core i7, but will just be using Westmere cores at the base, rather than Nehalem cores. Simple explanation, really."

Isn't Westmere just a code name based on the "Nehalem" architecture or am I missing something here?

Just like AMD "K10.5" is used in both Shanghai and Istanbul for example?
