They put out a survey a week or so ago asking for opinions on passes with different perks/limitations so wouldn't surprise me if they completely change the types of passes they offer.
This included things things like weekday only passes, can only visit certain attractions such as 3 of the theme parks, after 2pm only passes, different amounts of discount + family and friend offers.
Will be interesting to see what they come up with. Definitely seems they are slowly taking away some of the perks
