Hello, I'm back after not posting for a while, just to remind everyone who scoffed me off for this:

...that I told you so.
and I'd like to give a thought on WWW as a multiple level complex: maybe, like the second floor of the DADA classroom and Dumbledore's office in FJ it will be blocked off so that all the main visual effects and the Weasley twins can appear up there.
Also, I remember this coming up in a previous discussion it but was never fully resolved. We know there will be some use of a fog wall effect, jet-sprayed so an image can be projected on it, but will this be used to create the classic 9 3/4 wall entrance or will it be used like it was in
Pirates and be used to create the thieves downfall waterfall?
I beleive HTF did say something involving mirrors would be used to recreate the 9 3/4 entrance. For some ridiculous reason I'm thinking it might be a giant scale version of this:

Also, I noticed ReelJustice noted off the covered area because it was part of the "made up" Goblin Alley. Besides the fact that all of Potter is made up, I'm pretty sure most off the shops on the other side are still normal Diagon shops, including the exit shop for Gringotts. I believe all the goblin stuff is themed around the supposed outdoor show area, but I can't remember if anyone specified the exact location and where it was suggested that it would be called Goblin Alley or whatnot. Could someone point that out?
Although it doesn't look like it from the top, as it doesn't need too, I can see now the bridge to nowhere is an elevated train track meant to add to the cramp city theming of the environment, and I kind of like it.
