I'm still amazed how so few people have learned their lesson.
Remember this:
Remember everyone saying "it's just a rendering", "the dragon is a placeholder", "It's not really going to look like that"
At this point we are at the same stage as when the DA artwork came out. The land is cleared and the raft of permits is going out for construction to start. What you are seeing in that artwork is what is coming. Yes, there may be tweaks or cuts along the way, but that's what is coming and yes, it is an artists rendering, but it's based on the site plan that has been created and is about to become reality.
So, yes the arch entrance is what the entrance will look like. Yes, that is the way most of the things will be. Notice how close the Nintendo Land is to the model? This is what's coming. Just like the artwork of the recent past, it's probably all based on detailed computer renderings and models with some artistic license being taken, but most of it WYSIWYG.
