On a more interesting note, seems the four lands will undergo a bit of a makeover. Plus a new land.~
Leanbox seems to have undergone the most drastic change, dropping it's medieval theme and bringing in something more technological. Lastation seems a little less "dirty" than it's previous incarnation, but still pretty industrialized. Lowee, while still quite "magical" dropped most of it's fairytale architecture for more futuristic ones. Planeptune stayed relatively unchanged.
And the tower in the back of the Graveyard reminds me of Sauron's eye.
