Now while I give my own theory very little credibility due to how long Saw Alive has outstayed it's welcome and I don't doubt it will be any different this year; perhaps the reason why it stayed open this summer was because it will be replaced by a new maze this FN? I find it hard to believe Thorpe would close it at the end of summer to reopen it literally a month later- and since they have the existing infrastructure it wouldn't take them as long as it would to build an entirely new maze... or maybe I'm just clutching at straws. Regardless, I do find it hard to believe Thorpe would not give us any new mazes at all, and if Blair is the 'classic' maze they are bringing back I will be lowkey hella frustrated.
One final thought, I'm not very big into horror films or FN's pre-2015 but perhaps they are bringing back a maze who's franchise released a new film maybe??
