From looking all around the internet, it seemed to me that Intel was going to change the "i7 EXTREME" to the i9--- With an LGA 1366 form-factor.
I'm still going to wait a while (3 or 4th QTR) before buying it!
I KNOW as soon as I buy it, a NEW CPU will emerge! I LOVE INTEL!!! (And hate them at the same time)
A new CPU has already emerged
It's the new Sandy Bridge line which may be worth you looking into before buying anything new.
