Yes and No.
Raul is worse then Fidel (Both have hinted at this over the years), but Raul ain't exactly young, and by all the looks of things, while Fidel and Raul have set up a succession plan, I don't think Raul has (or wants to, or even can).
It won't be after Fidel that Cuba has freedom, but after Raul.
Sidenote: Raul Castro is the one who actually introduced Che Guerraro to Fidel Castro, and Raul Castro was Che's mentor.
....and Che was considered pretty much to radical for even Fidel.
