Will Having Castro Out Of Power Ever Change The Way Cuba Is Run?

Fidel Castro has been an enemy ever since he took power in Cuba. His dictatorship has never been a friend to the free world and so many have hoped that when he dies, things will look better for democracy in Cuba.

Foreign Affairs recently published an article pointing out how Cuba has not essentially changed since Castro turned over power to his brother. Does this indicate, in any respect, how Cuba will be operated when Castro is dead and gone (assuming that he isn't already)? I believe it does.
