The human eye is about twice as sensitive to green shades than other 
colours.  AFAIK, that's why they did it that way.
I guess (totally unsubstantiated) that one of the reasons why later 
iterations of sensors seem in many ways to defy physics in terms of 
clearly observable improved imaging performance in the face of physics 
that say it can't be done, might be big improvements in spectral 
performance of dyes in bayer filters.
