Unfortunately i wasn't able to get that many decent pictures due to my camera quality. But after being around the park and seeing the boards and advertising videos. I think i might have some ideas on what the new maze is going to be. (Sorry if this has already been announced or shown)
On some of the videos like the one just recently posted. You can see people trapped in cages looking infected. So maybe like the name "containment" its going to be a horror attraction seeing how long you can last inside. Also on the advertising board nearby for Containment. IT states it is a new timed scare attraction. Maybe meaning surviving a certain amount of time inside the container before entering.
On the building for the attraction there was a 2 light system ( one red and one green) with a buzzer i'm guessing to open the door. Also at the time, the queue board was outside waiting to be put up but again i couldn't take a decent image.
Besides the new maze, Cabin maze is by X again, Blair witch is in the rocky express area and the big top is on the beach. My bloody valentine is by where rush in the very corner right by the Crust shop, Honestly it looks very confined and out of the way there and i can imagine that area will be very busy.
This is all i can say. Hope this helps give an insight of the progress.
