One has to wonder if HHN 2013 was the test to see if they could pull off seasonal offerings in the backlot.
To me it looked like it was a HUGE success, so I could see a return of the Tree Lighting show, but in the backlot. This also frees up Universal Plaza for the return of snow or something completely different.
I think we will see the backlot used more and more as the park grows.
