Question About Power Torque Cranks

Looking at the Campy site they say that they no longer make the Power Torque bearing cups. If that it really the case of what use is the large number of new Power Torque cranks out there? I got was appears to be the last set of English Power Torque cups from an Amazon source. Questioning all of the many sources of Italian threaded Power Torque cups they all said that they could not get English threaded. I find it difficult to believe that they didn't make many more bearing cups than cranksets.
