That's the way it used to be, but all the big FW rides stay open until park close. We were there in April, the only FW rides that closed early at 7pm were Ellen, Figment, and LwtL. Everything else was open until 9pm.
Nothing has changed with what closes in Future World at 7PM.
The attractions that are open now until 9PM are the same ones as stayed open before the "change."
What DID change is that Disney no longer says "Future World closes at 7PM."
Even though Disney has now decided to change the way they
explain when Future World "closes,"
nothing ACTUALLY changed concerning which FW attractions remain open until IllumiNations begins.
---------------------------------------------------------
Now, just as before they "changed the hours of FW," (which, in fact, they did not do)
the following attractions stay open until IllumiNations begins every night:
Spaceship Earth
Mission: Space
Test Track
Soarin'
The Seas with Nemo and Friends Pavilion
Most every other attraction in FW still closes at 7PM.
