I'm pretty sure the screen shot that was being shared was from someone who had a 2 day, 1 park ticket in their "cart" ($210), and then showed MaxPass as being $20 (which is $10 per day of the ticket). I don't believe the system ever actually showed $20 per day.
I do think the price will go up, but I'm hoping they will at least improve the Wi-Fi beforehand! And if they waited for SW:GE, at least there would be some perceived added value to a price increase.
