There has not been much about it, one article in each paper maybe and not very much, moslty about the name, and oh btw he wont be HRH, Kings decision, interesting choice, break with tradition, lets move on to soccer
Most Norwegian are calm people and dont get all fussed up about such a decision (unlike some board posters from other countries it seems). He is a Prince, his sister is a Princess, not much difference at the time, the royals are *almost* never reffered to as HRH and HM in Norway its King Harald or just the King, Princess Ingird Alexandra or even only Ingrid. Maybe in 18 years or so we will see what happens but util them I think both children will do a few royal duties on major days, then they will focus on educaton and military service and who know maybe we are not even a monarchy then, one cant predict so far into the future.
I personally do not think King Haakon will elevate him unless something unfortunat happens to his sister or she cant have children
However if you want to read and intresting summary of the few comments in Norwegian media
Dag T. Hoelseth on the SRMB, has made and interesting summary, I will only leave the link
