I don't think anyone here knows (or the ones who know aren't saying, because they want to keep their jobs!). But the last time they made big changes from having just two levels of AP - the one for theme parks only and the one for theme parks + water parks - to having multiple levels, some with blockout dates, people who had vouchers for the theme park only APs were given Platinum passes, despite being more expensive, because those matched the characteristics of the passes they had paid for - no blockout dates being the main one I can remember. I'm sure that someone will come on and correct my potentially faulty memory of the details, but the point is I would expect something similar to happen if big changes are made to APs when they come back for general sale.
