That weight is without chainrings or BB. To compare with Quarq, add chainrings. 53/39 130mm BCD old Red chainrings that ship on Quarq Elsa are about 140g. Quarq tells me that the BB30 version of the Elsa is "10-20" g lighter than the GXP they list the weight for. With identical chainrings and spindle, and no BB for either, the comparison is 660g for Rotor vs 710g for Quarq Elsa. Still lighter but not as much.

JackDaniels, can you give us the weight of just the power meter arm so I can compare. Based on your picture I estimate it at 165gm.

The sisl2 are not in production at present. My stages Si 172.5 arm is 170 grams.That compares to my Si SL arm (non-stages) at 143 grams.
