Disney has basically set the precedent they can cap those APs as well, even tho they haven't announced that stop at this point. So Disney can accept a number of them upgrade and then cap that too.
The thing about the crowding is... remember it's not just about total number of APs.. it's about the visiting patterns. If the same number of passes aren't crowded into the same limited available windows... crowding is lessened.
I look at this as Disney *finally* tipping their toes in the pool about altering the AP calendar and model they use. It's hard to step in front of the gravy train.. but looks like TDA finally got some balls to do so. Their motivations may be something different.. but time will tell
