In the Netherlands i sometimes wonder if they will go back to the old traditions when we get a king again, and call his wife queen, or if this will be taken as an oportunity to modernize the wording, and let her stay a princess.
As a background, the Netherlands has had 3 consecutive queens, and no king since 1890. In the last 120 years there have been enough changes in the gender roles, ti justifify completele equalizing the rank of king and queen.
