Oh I think these stages here are huge...but I am sure you are right that moving stages will be back. I personally hate moving stages...they take the action away from fighting, and make you focus on surviving the level. I know that is just my personal opinion, so I am ok with people disagreeing with it.
But all these new levels shown so far, are quite unique, and add some great positioning options, and an enviroment you will want to play in over and over again, as they are literally moving works of art with a story to them.
