Castro: Dying?

There are reports out that the Cuban dictator, Castro has little time left on this earth. Officials believe he has cancer of either the stomach, colon or pancreas. Without chemotherapy he has maybe 3 months and with it maybe 18. The question then becomes what change will there be once he's gone? The U.S. is preparing for all different kinds of possibilities including mass migration to Miami. In all likelihood however, there will not be much change. His brother Raul Castro, is the most likely successor and there are hopes that he might bring change to their faltering economy.
