Hello All
The E60 as far as I am aware has the same sound engine as the E80, but has less on it.
You can see my personal report on the E80 and PSR 3000 here. http://www.synthzone.com/ubbs/Forum37/HTML/013261.html
As an addition, I would like to add that I play a Wersi OAS instrument with OAS 6, (Shortly to be upgraded to OAS 7) and none of the other manufactures new instruments would cause me to change, therefore I have no axe to grind with any of them.
