Fidel Castro steps down

It has been a long spell for Fidel Alejandro Castro Ruz born in August 13th 1926. He has been in power in Cuba since 1959, but today he will resign his post to be replaced by someone else.
That person is likely Fidel's brother Raul, but that will not be confirmed until the end of the day.
Raul has been acting President of Cuba since July 31st 2006 when Fidel became reclusive after surgery so chances for him are good. Question is: Will Cuba change under Raul, or will it be an extension of Fidel and his dictatorship? Time will tell.
