I think they're a fourth, cause while AJ and Pinkie became crystal ponies after the crystal heart was put back in place it disappeared. The ponies actually living in the empire had gradient like hair and could turn crystally again on their own as long as they were happy and not afraid or sad. So saying they're a fourth species should be accurate.
