I heard recent news that would confirm what you are saying. AMD faced 
big problems during the development of its next quad-core and will 
release it with a big delay (several months). The Nehalem will be 
released soon after that and will already represent the next generation.

This is what I've heard, but I don't really know what the implications 
for the MITgcm are.
