Thanks for the feedback, guys. Based on the previous release cycles (SB, SB-E), I have observed that RAM prices actually tend to increase by a certain amount during processor launches. I don't have any hard data, but believe me... I have been procrastinating my CPU upgrade for quite some time now and follow the prices on the Web closely. IMO, retailers actually have an incentive to not drop prices during processor launches because they have a high probability of pocketing those slim margins.
Sure, in the long-term, prices will continue to go down, but I don't want get desperate on launch day and spend $50-100 extra on a pair of RAM I wasn't planning on buying. I got a reply from Kristian Vättö, confirming that IVB is is dual channel and supports up to 1600 MHz (straight from the Intel roadmap).
I'll be on the lookout for RAM deals in the near future here because it looks like IVB is very much going to be on time.
