Italinan threading is not uncommonon current bikes. There is Campy zero stack type internal HS that is a campy standard for which others have produced compatible knockoffs. Otherwise 'campy compatible' is meaningingless with respect to a typical non integrated or internal threadless HS system. If someone threw that 'campy compatible' jargon at me I would not have a clue what they might be refering to.
