The Aircraft Commerce article referred to by CargoOne also said that, while SQ and EK assumed that they'd be able to charge a premium for A345 non-stop service, they haven't managed to make it stick and now charge the same business class fare as the one-stop services. Thus the high seat-mile cost aircraft isn't pulling in a premium to pay for it. Article also said that long-haul hub bypass wouldn't work as at least one end of the route would need to be a large hub in order to generate sufficient high yield pax. All these comments would seem to apply to the 7E7 (long range variants) and the B777-200LR too.
