Even if Siemens doesn't sponsor it anymore, it's a giant ball at the entrance of the park. They will NOT tear it down or anything. I think Spaceship Earth is safe. Journey into Imagination, however... I'm not so sure. I'm kind of hoping they say something about it at
D23 about how beloved Figment is and how their bring back Dreamfinder and making a more up-to-date version of their ride from the 80s.... a girl can dream.
