Very unlikely, if you ask me. Sorgenfri is in need of renovation and the royal family has shown no interest in the palace since the death of Princess Caroline-Mathilde in 1995. Each time the throne changes hands, negotiations are made about which state-owned palaces the new monarch will have at his/her disposal, and I wouldn't be surprised if the new king relinquishes the right to use Sorgenfri. That being said, I do hope that Sorgenfri will be Crown Prince Christian's future residence. He is indeed expected to take over Queen Margrethe's mansion at Amalienborg, but she may live another 10-15 years, and the mansion will likely need renovation before he can move in. If the renovation of Sorgenfri is initiated earlier, it could become his first home.
