The 'First Family'

I found this article which gives brief descriptions of Kim Jong Il's 'secretive' family. I didn't know he had three wives and three sons, who are virtually kept completely out of the spotlight. It would be interesting to contemplate, if it were to happen and is probably likely to happen, which son might succeed the Dear Leader and how the son will go about in achieving the same kind of legitimacy, the god-like images, his forefathers had.
