The T9000 transputer (which is superscalar - with a vengence) uses a 
3-level-metal process.  I would expect a significant number of
the next generation of processors to be implemented on three (or more) layer 
metal processes.  High density, high connectivity, three layer processes, 
like that used for the T9000, offer very high transistor density; they 
are very attractive for large scale logic devices.
