Throwing out a theory as a bit caught me in interest. Especially in contemplating with the change in queue flow with SS15 with DND.
Can be wrong, but it looks like in comparison to how H-Lot North shot people infront of H-Lot South for Scarecrow's case (And like how it did similar things when it was the Texas tent), it seems they'll be shooting people out to the Super Nintendo World/SS15 side of the soundstage as opposed of having guests exit out into the side against the soundstage.
Personal speculation: I wonder if they might be doing a queue reconfiguration for both SS15 and T-Pad; using the smaller story that is Scarecrow to faclilitate the ability to do this. Allowing the area in-between SS15 and T-Pad to become a TM access point instead, and having guests hug the soundstage as they turn left to face the way up to Super Nintendo World's entrance.
With Fan Fest Nights having Super Nintendo World as a core part of event offerings, I wonder if the exclusivity for Day/Night is finally over for the sake of Nintendo. And in so doing, USH is in a position that requires them to redo the exit flow as a resultant of having Mushroom Kingdom operational during seasonal events going forward.
If that is right, then it would make sense to necessitate a change in exit configuration for T-Pad in the process (and in doing so, possibly SS15's queue configuration too if they follow the DnD Queue configuration that seems to be happening now.
This is all personal speculation; but I can see logic in this as a byproduct of them wanting to ensure they can get optimal space use. Especially if it allows say, a larger use of SS15's space to allow larger setpieces to be much more aptly in place going forward.
But that is ofcourse--my tea.
