It appears that some work as begun. When we were there in Feb. (President's Week,) there was plywood up around the entire center of the hub at the end of Spaceship Earth. Sorry I can't give more details than this.
I just got back last night. The area is still blocked off with the wall. I didn't see or hear any work going on behind the area. There is a sign that says coming soon or something like that.
We were just there at the end of Feb. and, other than the sign on the wall that Seimens was the new sponsor, I saw nothing different. There's been a wall there for quite some time anyway and I heard nothing beyond the wall.
