Wow I was way off. I thought the 2 circles one was for Space Pavillion and the one with a diamond in the middle was for Galaxy
I think you're right.
Also notice that the 12 icons are arranged in groups of 4, each representing one of the neighborhoods. The ones on the left (greens and yellows) must be World Nature (Seas, Moana, The Land, and ?Soarin?). Not sure what the orange earth icon is.
The ones in the middle are World Celebration: Interlocking bridges (Odyssey), Tree trunk looking thing (Fesitval center), Spaceship Earth (duh), and Imagination (old logo as well). They're represented by blues and purples.
And then the right side icons are reds and pinkish-violets: World Discovery. You've got the old WoM icon, so that's probably Test Track, then there is a double circle whirly thing, which invokes a centrifuge to me, so I'd think Mission Space, maybe Play?, the one with the diamond in the middle is probably GotG, and the other one is either the Space restaurant, or Mission Space itself, if the circles are Play. Kinda unsure about these.
Which means, not sure what the new attraction is other than Brazil. I really hope it's not the carousel at the UK pavilion. That doesn't seem to merit a poster.
