Don't mean to cause any confusion (previouse post amended), mainly want to say I think it will cost more than the Sandy Bridge at launch.
Just because it cost less for Intel to make them doesn't mean they will charge you less. It hasn't happened with the SSDs, GPUs, or bank interest rates
its competition that drives down the price. You get charged with what ever the company think they can get away with. Of cause there will be an increase in performance so you could look at it as you are getting more performce for your money.
