Hi Andy,

"Nehalem" (not Netalem) is a codename for the successor to Core 2 (specifically, the 45nm "Penryn"). It represents a "tock" on Intel's progression, meaning that it's a microarchitecture modification. The "tick" that followed it, ie the die shrink from 45nm to 32nm, is codenamed Westmere. In other words, it was released a long time ago (2008) and has been superseded by two releases since.

Intel uses Xeon, Core i3, Core i5, Core i7, Pentium, and Celeron model categories to segment its processors. They've been doing this for a long time, although the designation moved from "Core 2" to "Core iX" starting with Nehalem. These differ in features like core clock speed, memory/FSB clock speed, core counts, thread count (Hyperthreading capability) and L3 cache size.

So it doesn't make sense to call a new processor design Core i9, but Intel could redistribute its market segmentation to include a new Core i9 category (or any other name). There's already a Core i7 Extreme so it's not that far off.

There are tables here that show how the differentiation works, in addition to TDP and price, for Nehalem and Westmere:

And for Sandy Bridge:
