A new stage has been released, Pictochat. Doodles will be drawn and you can stand on them. There are a few affects the stage has like wind blowing and a skateboard moving to and fro.
I agree with Koehler... The stages are the one thing I would change in this game, I don't really like any of them that much, it seems as if they arent as simple as before, there are few of them that don't ever change. I sure hope hyrule comes back as a past stage thing, or maybe they'll remodel it, because this Mother 3 stage just isn't as good in my opinion.
