Customers seem to be adopting the MX line very quickly.
I'm not fully aware of the price difference but I believe that on a high end servo (28/64) the price difference (in terms of percentage) is not significant and the MX line is superior, especially because it won't lose precision over time.
In the example you gave me (a Robot arm), using Potentiometer based servos is usually not the best idea, especially if the arm will be doing a repetitive movement.
This is because the repetitive movement will cause localized wear on the potentiometer thus reducing the accuracy and increasing vibration as the potentiometer wears out.
We actually have a customer who builds animatronic creatures for museums and they were very keen to move to MX servos especially for this reason.
