I think it is a media attempt to make her more accessible to the everyday woman/man. The Duchess of Cambridge sounds so formal to most (though I would love the title! Just teh title though, not the man).
Princess Di was used because she was considered the
Princess of the people, this is an attempt at re-creation.
