If you thought that Nathan was kidding about villagers turning into zombies, you were wrong. Progress is being made on the shapes and sizes of them, and Nathan Adams showed us a picture of a baby villager turned to a zombie. Nathan described it as, "the cutest little terror ever!" He also said on his Twitter stream, "Currently they're really fast (almost as fast as a sprinting player) and won't age. Also, they don't burn up in the sun, but that may change. They'd be pretty rare because you'd only get them from zombies eating baby villagers, so I'm not worried about making them too difficult." Are you excited about zombie villagers in Minecraft 1.4?
