I believe the reason why people want a glimpse of BD and its performance (only if a sneak peak) because AMD doesn't really have a stellar record in keeping promises and meeting deadlines on CPU side of things.

With Intel, I am sure SB is gonna be rock solid. The chips are already out there in the wild. we all know how they are performing. Enthusiasts usually get to know about what is in store for them when it comes to Intel CPUs. If Intel says SB is going to come in January and if I am waiting for the chip for new build, I can go out and get it in January. There is assurance in waiting here.

With AMD it's not so. I can wait till Q3 next year for BD and (I sincerely hope it's otherwise) may end up disappointed. This is the reason why people are clamoring for some info on AMD CPU.
