Biggest unknown is the what DDR3 will do for Deneb in terms of performance, when comparing to competition both C2D & Nehalem , this may effect the pricing of Deneb.Amd will price Deneb keeping this "DDR3 FACTOR" in mind, even though ddr2 parts are coming out first , then ddr3 parts coming later.

So initially if Deneb is overpriced may be its bcz of the "DDR3 FACTOR" which comes later next year.

But I could be 100% wrong.
