It's really hard to forecast next year because the system is likely to be revamped.
Sure it's profit centered, but currently they are playing with levers based on demand and expected value.
For it's flaws (6:50 AM wakeup call, price, etc.) - it's way more valuable in terms of line skipping than FP+. To get 4+ valued Genie+ LL is pretty simple and for other guest who want to maximize value, they can get a dozen at MK.
Just wait till you have to tap into Muppets and BatB to get another LL. I'm hoping they re-think their current plans.
