As to 8 versus 10 studs, I would guess that is determined by wheel availability.
Hispec is the supplier and they do not list 10 lug wheels.
According to MOR/ryde - for comparison the outer bearing on the 9K is the same size as the inner bearing on the 8K.
For comparison these are pics of the 3 IS axles DRV uses.
