I don't know ... probably the XPS series and the mobile versions in the XPS and AW laptops. It seems to be placed as the new mainstream, so it should eventually replace most everything.

P-67 Sandy Bridge is the latest thing so it's a little better than everything before it, but compared to the X-58 (LGA-1366 Enthusiasts Platform) is not the big jump that people think it is.

Looks like the Aurora might be lost to mainstream performance (good enough), but hopefully at least one machine (the Area-51 maybe?) will be reserved for the best Intel has to offer: SnB-E (Z-68 LGA-2011). We should also see the announcement of the new high-end and extreme LGA-2011 desktop processors. Of course (as the article says) ... all this will come later ... Q4-2011.

RE: Sandy Bridge - E  (Z-68 LGA-2011)

Since this version isn't released yet, alot of this might be sure speculation on the writers part, but if you search the net a bit you find mentions like:

This socket is expected to be released alongside Sandy Bridge-EX in Q3 2011, and will support 4 memory channels as well as 40× PCIe 3.0 lanes.

Desktop Core i7 Extreme : 8 Cores (16 Threads)

There's a fair wait for the Sandy Bridge with a staggered release over 2011. I vaguely remember a mention of one of the laptops at CES containing a Sandy Bridge processor.

Sorry guys but you don't get my sympathy about your systems not being particularly upgradeable due to a new socket requirement.  I bought my Area 51 ALX only 2 months ago but I also bought it with the practical reasoning that it would invariably be outdated (the question was just "When?").  I guess that is why whenever someone asks me for advice about purchasing a computer I always tell them to look at what they want it for first and buy what they need, not what they want.

I'd be very surprised if the top end i7's will be incapable of running up and coming programs and games for some time yet.  Very surprised indeed.  Especially with the new Windows set to be "OS on Chip" compatibleand other new developments that will be readily available and useable for us.
