Right now he has two choices: he can flee or he can be killed.
Either way, its the end of an era.
My guess is he grabs a bunch of gold, takes a couple of planes with a VERY well paid off flight crew and heads to Venezuela. I believe he is a chicken at heart and will run rather than die, Chavez will probably give him a few thousand hectares with a quaint little hut and a big yard to put his tent up on and let him retire.
