They use to, remember when Germany turned into a gingerbread castle? would love if they did that again. And I would still love (in my fantasy head) to see Norway and Morocco outlined in the lights (I know M can't because of its religious significance, but N didnt because at the time they (sponsors) didnt want to pay for it to be added in.
I know it’s doesn’t necessarily mean anything but from the Epcot experience preview it shows the pavilion outline lights fading in and out in a way we haven’t seen before. That’s what made me wonder if there are being updated.
