W&C will adopt five children to make up the necessary numbers for the new generation of the monarchy as it has slimmed down too much with deaths/Yorks/Sussexes. If not then Louise, James, Beatrice and Eugenie will need to be roped in.
Meghan will remarry possibly Elon Musk or President Trump and continue to laugh at the RF.
Harry will remarry another cable actress. His children will mysteriously never be seen or heard from again.
Andrew will try to rehabilitate himself possibly by rejoining the military or even the clergy.
C&C will make increasing use of technology as their ability to do things in person declines with age/health. There will be multiple android versions of them in use or if technology is not up to this then they will use Lookalike impersonators instead and tell them what to say remotely via microphone ear pieces.
Sophie will wear some iconic outfits.
Fergie will start some new business ventures.
Charles will give a few racehorses to Camilla but will sell most of them.
The Royals will pack in shooting hunting and fishing.
