Good question. Don't know the answer though.
But I do know that you can find new or slightly used Rival cranks that are more than half that MSRP price on the Bay. Don't buy it new, it is grossly overpriced.
I don't even know why SRAM has all of those standalone cranks. Too much overlap if you ask me.
