When I was there for EMH on the 16th, World Showcase still closed at 9 just as Illuminations started. The rides in Future World closed at midnight. I know Universe of Energy, Soarin, Test Track, Mission Space, Spaceship Earth, and (I think) Living with the Land were all open, and my hazy memory seems to be saying Living Seas and JIYI were open too. Although I can't quite figure out the point of LS staying open since when I was there at night on my trip before last, the lights in many of the tanks (such as the manatees) had been turned out for the night so they could get their sleep; and that was relatively early, around 6:30 from what I can remember.
