timeline for 4,8,16,32 core PC processors? back

It seems that the multicore trend has picked up a lot of steam in the past few years and intel obviously has some tricks up their sleeve as they've made a prototype 80core processor, and are pushing the quad cores now.  What I want to know is, when will we have more?  All the intel roadmaps I saw pointed to dual core and quad core for the foreseeable future (2 years?), with 8 core still only available by using dual quad core xeons.
I know there's some people on here with insider info, and obviously that can't be spilled, but I suppose i'm hoping that I've simply missed an important announcement or roadmap somewhere that says when 8 core single cpu or more are going to be on the table.
BTW, looks like apple announced their macpro with 2 2.8ghz quadcores (1600mhz fsb), for $2800 USD.  WOW.  The parts alone nearly cost that much if you wanted to build your own.  22ghz of power for $2800.  Nice.

By the end of this year we should have native quadcore Nehalems (8M shared L2, 3-channel DDR3-1600 connected directly to CPU) that have SMT giving making them look like 8-core CPUs. I'm not sure how big boost will SMT give it though.
I don't expect to see real 8-core CPUs (16 with SMT) before Intel goes to 32nm some time in 2009. By that time we should also have [LINK http://ompf.org/forum/viewtopic.php?f=3&t=486 Larrabee] (scroll down,  bunch of links there) with lots and lots of cores (x4 with SMT) [SMILEY :)]
[edit]
About that Apple, this is awesome! Though I'd probably build something myself with two of [LINK http://www.newegg.com/Product/Product.aspx?Item=N82E16819117149 these] Sure, they are 500MHz slower but also $450 cheaper per CPU [SMILEY :)]
Let's see. 2x300 for CPUs, 300 for motherboard, 170 for 4G RAM, $130 for PSU and ~300 for decent water cooling, the rest I can take from my current PC. It totals to around $1500, not all too bad [SMILEY :)]

Funny, I myself was going through this in November when the E5410 was released. I bought two of them (I paid $340 each) the day they came out but now they're stuck waiting in a corner since I'm debating whether or not to go with Skulltrail motherboards ($600+ motherboards? Um..). In the meantime, I have quad core workstations on the network to play with  [SMILEY :mrgreen:] .
And Ho ho, I've read through the roadmaps for Nehalem and from what I'm seeing with Intel & Nvidia (neither facing competition from AMD), I'm willing to bet that the releases will be pushed by at least a few months if not a full quarter. I'm betting on Nehalem coming out in Q1 09 at the earliest. There is simply no reason to launch new processors that have relatively the same profit margins. Nehalem is still 45nm therefore production costs between Penryn and Nehalem should be very similar and Intel will only make more profit by forcing consumers to buy the old Penryn stock (funny I talk about Penryn being old when Q8x00s aren't even out yet  [SMILEY :roll:] ).
OP, 16 cores+ is possible right now by using Tigerton (MP) processors - these will allow you to have multiple processors on a motherboard but that privilege comes at a huge price. The cheapest quad core Tigerton costs $800-900 while the cheapest Xeon (DP - meaning dual processors per board) is $200-250. Sun, IBM etc. sell a few 16-32 core systems iirc but they cost in the $10k+ range (purely for server environments).

I doubt that Intel would delay the launch. During the last year when they had no competition they brought out most of the stuff on time and some even sooner. Also Intel desperately needs direct connection >=2P platform and Nehalem will give that.
