Since the embargo juste lifted today, id expect another month or more untill ALL partner cards are known. Because of this, it is impossible to say right now, but i wouldn't expect evga to make an ssc 2070 super.
The 2070 super and 2080 reference models are very simmilar according to a teardown from gn. Same card dimensions, same tu104 (i think) die, same power requirements, same vram amount, just slightly cut down specs. Really no new products, but a 2080 refresh with lower prices. Im very exited about the lowered prices tho. Finally brings rtx value to a good level.
EVGA doesnt make an ssc 2080, so i dont see why they would make a close 2070 super. It is possible tho.
