Shiet... Itll come in due time. Intel has the market totally. Why would they release it anytime soon? AMD has ALOT of catching up to do and it will take awhile (probably atleast 2 years). Just like back in the glory days of Socket A. Intel lost it to AMD for a few years.
Once AMD can compete for performance again (I know, some will argue they can, but come on they cant right now. Price to performance is the only thing they have going and thats not even that good w/ i5 deals to be had every week), I think Intel will bring about "Larrabee".
