Now corporate shops will hesitate to commit to AMDs 64-bit chip because of speculation about whether its instruction set will be compatible with Intel's.
Pair that with Microsoft's delayed 64-bit Windows launch, and you've got another well played round from Intel.
It's likely that this was only a contingency plan, though. I'm sure Intel would have liked the world to move to Itanium, but this is their second choice of outcomes. AMD gains some market share for a brief moment, but then potentially has to backpeddle to design Intel compatibility into their already completed 64-bit offering.
