She is pregnant so I won't dish on her ... (bad timing, Sofia, bad timing :-)). I am still puzzed about all the publicity they are getting. It should be Viccan, Dan and Estelle ...
I think they get a lot of publicity because they actively seek it. Without publicity their roles really are redundant as they have no great importance in the grand scheme of the SRF. Plus they are attention-wh*res. They love and crave whatever attention they get because it is the only way they stay relevant within the limelight. And I don't think that CG, the Court or the Media are strong enough to defy them and not give-in to their demands at publicity. In fact, I think that the approach given to CP by his father and others over the years have incubated and encouraged his desire for attention and publicity.
Vic and her family, on the other hand, naturally incur publicity because of their status as the heir family. They are relevant because of this, and naturally people are interested in their lives as, one day, they will be the 'Royal Family' of Sweden. But their personality and ethos seem different: they do not seem like attention-seeking people. They seem to live their lives happily away from the spotlight, and don't crave that vain attention.
It will be interesting to see what happens when Vic is Queen and her family is the main interest. I do not think that Vic is strong enough to defy her brother and SIL's attention-seeking, but I think that a natural change will occur in how the public perceives the gruesome twosome as they lose whatever relevance they had. That is when I can see all kinds of PR games and stories being leaked to the press by CP and Hoefia: because that is the only sphere in which they will gain the attention that they so seek. They have already done this with Madde, and it is appalling at how it has been allowed to happen.
Ultimately, it is Vic and her family who will be remembered by history. Even now we remember little of the siblings of recent Swedish kings unless they became an influential part of court or other royal families : who remembers Carl Johan, or Prince Wilhelm? In time, CG's siblings will gradually be forgotten about, as will CP and Sofia.
