By rapidly appointing two heirs, Saudi Arabia's King Salman has pressed pause on "succession Sudoku", as one leading local journalist calls speculation over whose star is rising and whose waning in the large and secretive Al Saud ruling family.
The choice of 69-year-old Muqrin for crown prince and 55-year-old Mohammed bin Nayef for deputy crown prince resolved the most important dilemma in the dynasty's recent history - how to jump from sons of its founder, King Abdulaziz, to his grandsons.
Yet while much attention has focused on the naming of Muqrin and bin Nayef, less noticed moves have indicated broader changes in the contours of how the Al Saud manage their power and which young princes might rule the world's top oil exporter and key Western ally in future.
After decades during which top jobs were held by the same handful of people, these appointments appear to set in place a new ruling team to dominate Saudi politics at a time of unprecedented regional turmoil and long-term challenges.
The most important change appears to be the creation of two new super-committees that give Mohammed bin Nayef and the king's own son Mohammed bin Salman extensive control over most aspects of Saudi policy making.
Mohammed bin Nayef, who is also Interior Minister, now heads a committee on politics and security that will develop Saudi strategy on how to tackle Iran, Islamic State, wars in Iraq and Syria, the crisis in Yemen and treatment of domestic dissidents.
Mohammed bin Salman, who at age 35 has also been named Defense Minister and head of the Royal Court, heads a committee on economic and development policy that makes his voice the most important on big long term issues confronting the kingdom.
