For the record, it was never labeled "Passholder Previews" because the group also included hotel guests, military personnel, and VISA cardholders. It was only marketed as "Previews" without any exclusivity. APs get the same number of allotted, and "discounted", tickets. The only difference now is that your day will also include GP.
Despite that, I agree with the frustration with communication.
I disagree about the inclusion of the GP. That's all.
