"There's a bunch of analysis of costs and such floating around since
the leak, but here's the distilled version of it. The die size is roughly
the same, and the wafers haven't changed diameter, so with double the
capacity, we're talking a neat 50% drop in cost per GB. Keep in mind this
change won't happen overnight. The fab has to make its money back from all
of the R&D and retooling costs needed to make the transition. Because of
this, we won't see the price slashing that took place with the move to 34nm,
but over time prices will drop as production ramps up and the old process is
phased out."
