2017 Series Yellow
 

Spoke to the dealership today and in the US there is currently no build date for the series yellow. Current build dates in their system cover all the way through December.
So it appears there will be no Series Yellows running around until at least January in the US.

odds are they are not coming out until the pp comes out, since they are equipped with it. Subaru is finally learning not to put the series editions first. It only took them a few tries.
