Exciting times, true believers! Universal has filed a notice of commencement today which I believe is for the Gringotts ride track. It can be seen below.
Here's their official site: http: http://www.mosleyerecting.com/index.html
So there we have it. We should have track going up inside the building sooner rather than later.
Universal also filed 2 other NoC's, one for the replacing of a kiosk in KidZone, and another that doesn't have an attachment yet. We'll keep you updated on that one at @Parkscope.
