just got back from a week down there, and i have some interesting hopes. Somethings i noticed.
as it looks was mentioned earlier, It appears that between Thursday night and Friday morning the constructions walls blocking the view from the queue area into the new graveyard were removed. They also placed a new dividing wall in the center of part of the queue that has one side continuing straight past the new addition, and the other side which funnels you into the new crypt area. The "new side" was blocked by several plants, but you could still see into the new area.
I asked a CM about when it would open based off the changes overnight, and she told me that the only thing they were told is that they are doing testing and it should open in the next month.
Also noticed:
The hitchhiking ghost section, you can see a pair of cameras now poking thru holes cut in the wall abover where each mirror was located. (and above the current curtain). There is also a big infrared lighting bar using LED's above the camera location, which would likely be used to light the doombuggies passing by. Personally, I don't know what to expect, but honestly i'm hoping if they do something animated it doesn't look so cartoony (casper-ish?) as the current animations. There was just something about the old figures that the new animations are lacking.
I also was able to see into the "servant quarters" area used to move wheelchair guests between the ride exit and the stretching rooms when i walked past on Friday. It looks like something is going on in there too since I it looked like the walls were all covered by black curtains.
