WHERE is your proof that it is delayed EVEN BY A DAY?! Do you work for AMD??
AMD sampled 90nm Opterons a few months back with power consumption at normal speeds being a little more than half of the 130nm version (40W, IIRC)--they are certainly capable of pulling out a mass production 90nm from looks of it (especially in comparison to Intel's flop a.k.a., Prescott). From all evidence, Troy, 8xx and even 1xx are still on track for a dieshrink this Q2 (or early Q3, likely depending on Xeon CT).
Again, where is your evidence that there is any sort of delay?!
Maxtor disgraces the six letters that make Matrox.
