I was just able to obtain this first look at the construction of the D23 Expo:
UPDATED WITH MORE PHOTOS!
It may not look like much at the moment, but let me tell you why this is BIG news.
I'm involved with a lot of trade shows for my real life job. The average show is put together completely in about one and a half days (or less). The fact that Disney is already beginning booth and pavilion construction is a sign of VERY big things indeed.
Put on your happy faces folks, the D23 Expo is really REALLY on the way!!!
You saw it here first folks!
