Intel's new "Core" architecture

Ars Technica has a fantastic, in-depth review of Intel's new "Core" architecture, which makes up the guts of the next generation processors that will be powering Intel-based PCs and Macs beginning later this year.

One point of confusion that I have not been able to address- are the Core Duo and Core Solo processors that Apple (and other manufacturers) are currently using in their Intel systems based on the "Core" architecture? From what I can gather, I don't think they are.
