No insider information here, just pure speculation:
HRRR construction is a real thing that will impact queues and such, but I just don’t see how that entire area is going to be closed so much that it causes the Tribute Store to move. There’s two house entrances right there as well, yet nobody is talking about those getting relocated.
While I’m sure the Mummy team may like their queue space, who’s going to get the final say when only one of the options turns that square footage into profit?
My prediction is that the Tribute Store remains in its main spot. The arcade will either be a secondary retail location, or tied into a FNAF “experience”.
