Yeah, AK and Epcot will be exactly the same, regular hours wise. It never changes.
MGM...depends on how many Fantasmics they have on a given night, but sure a hour, here or there.
MK is always the wild card and jackskellingtonsgirl pointed out. You can't accurately predict which days Wishes and Spectro will be. You can't accurately predict what EMH will be like with
MNSSHP thrown in. The crowds...shouldn't be a deciding factor into whether to release hours or not.
EMH is what I want to know, specifically to avoid MK PM EMH and to definitely hit MK AM EMH. I definitely hope that they don't pull a fast one like they did on my June trip and have double PM EMH and only an AM EMH here and there. The more AM EMH there is, the happier I am.
