I'm more amused by goblin villages myself. I'd assume this would be a mob that acts like a player character? Able to live on its own accord in groups, breaking and building, then wandering and guarding?
Doubt it, probably just basic village layouts with a goblin spawner in it.
Second, Notch needs to put in something along the lines of the Colossi from Shadow of the Colossus. Then, someone needs to landscape a huge island like the Forbidden Land, and re-skin the textures so that we can have brown and bloom-ish feel.
Profit. Even just the colossi would be good enough.
