A slightly clearer picture has emerged as to how Intel intend to play ball with its soon to be released Nehalem architecture. Nordic Hardware has gotten hold of an updated roadmap which introduces a few minor changes to what we've been indicated about its release formation in the past.

At the current time of writing, Nehalem will debut in early November; which date exactly is not yet known. We knew to expect the top dog Extreme Edition 3.2GHz Bloomfield model on launch day (shifting at $999, ouch), but thankfully for us souls with pockets not so deep, two performance and mainstream chips will accompany it, these being Core i7 2.93GHz and 2.66GHz parts priced at $562 and $284 respectively.

The other interesting thing that the roadmap shows is that these three processors will be the only models available using quad-core Nehalem architecture until late next year when Lynnfield and soon after Havendale (dual core with one GPU core) arrives.
