AWESOME UPDATE!
Time: 9:00 AM California Time, Wednesday
Lots of new features now!
New Features: The Big Spinny Thing on the Ceiling from Nats is there, there is framework for what I think might ACTUALLY be the art gallery, dunno what the other stuff is then, some posters are getting ready to be set up, some of the boxes are now open, there are desks that I believe to be registration desks, I believe the beanbags have been moved to the beanbag room, but I wasn't allowed to go upstairs, and lastly, the flags for every country participating are being set up.
Also, there was a copy of the floor plan laying out on a box!
From what I saw, the room is going to be divided into the 3 age division, each one color coded differently using Red 10-, Green 11-14, and Blue 15+. I didn't get a chance to see where side events like prereleases would be held or anything like that, but I assume they'll be held at one of the sections once worlds isn't using those sections. Then again, I don't think I saw the whole map.
Next Update: Tonight or Tomorrow if possible
