Ivy bridge is a mainstream 22nm cpu.This is something like the 2600k is today. I would not imagine you will see a bunch of cores on this (more then likely 4 or 6).Price point will be about the same as the 2600k. SBE is an enthusiast grade cpu. it will replace x58 . This will be 8 -12 cores. the FIRST set on this plat form will be 32 nm. This should be released q3-q4 this year. The 22nm version of socket 2011, will be released in the first half of next year. Think tick tock. tick being New platform Ie socket 1155 or 2011, tock being a die shrink. So ivy bridge is basically Tock on the 1155, and SBE is a Tick on socket 2011. This is what most of my research says to me. I hope this helps.
