I wouldn't say zombies were originally brain-eaters (that came much much later), though they were supernatural. In folklore, they were just re-animated corpses brought to life by magic or supernatural powers. What we know today as zombies, whether diseased or not, were basically invented by George A. Romero in 1968, though he named them "ghouls" back then. He took away the mystic nature of the myths and made them realistic. Anyway, the HOTD zombies are based on Romero's zombies, so I don't think we'll see ghosts or anything like that.
