As we all know pigmen as vill. will not be added so how bout adding the sky zone as it was and having normal pigmen spawn there holding iron swords(oppisite of gold) and instead of ghasts dragons.Unless Notch adds them in villages as well...
Minecraft is all about originality and I've had enough with pigmen with them being in the nether. What about glass castles near the 120 y-coordinate filled with manbearpigs?
