I can't possibly think that people would assume Disney would discount their existing AP contract at all though, right?
I get that there is the looming fear that people won't be able to get into the parks, but we don't know what the reservation restrictions will be. Disney has painted a picture of the worse case scenario that an AP won't be able to get into the parks, but who knows what demand will look like a week after opening.
If you're unable to get into the parks on the day that you want to, I'm sure Disney will refund the $2.74/per day that you're paying. Other than that, why would they discount APs because of a new reservation system?
