I don't know but I think that the Kuatan Palace stage from the previous game is returning in MK:Deception. I had been gone from this site for over a week and I just took a view at that new trailer that featured the Dragon King.

One of the Death Traps showed a chacter get knocked into a moat filled with lava. The stage had statues of Shokan warriors just like in the Kuatan Palace stage in MK:DA. I think that some stages are going to be imported in MK:Deception from the last Mortal Kombat title.

I would not be suprised if we see a tweaked version of Shang Tsung's Court with the Buddahs that spit out acid. Mabey there would be a death trap to that too? And I remember reading a profile for one of the stages in MK:DA that said a dragon lived under the stage and it feeds of the defeated warriors that fought above it. I believe it was the water stage but I might be mistaken. However,I have come under great suspision that MK:DA stages are going to return as hidden features in this game.
