I have yet to see a good explanation of what advantages a .18 micron process gives.  Canon has the capability, so apparently they have not been seeing a compelling reason either. 
My first thought was that wiring traces that must run between pixels could be made smaller, and on chip transistors could be made smaller, but I have read that it is not possible to make the ground and power traces  smaller due to crosstalk and voltage issues unless you adapt Canons new patent for a rear illuminated sensor.  The transistors could likely be smaller, so thats a incremental improvement.  Using more of the available surface area for photocells is obviously a good thing. 
I'm certainly all for new technology if it improves the sensors, but not for new technology just for its own sake.
