AFP reports on "doubts" about Kim Jong-un succession

The report though seems mostly speculative, and I'd say the main claim in the headline isn't backed up by the rest of the story.

Heck, I'm not so certain myself that Kim Jong-il can pull off a second dynastic succession, to a twentysomething no less, when so much of North Korea's elite must be aware on some level that the first one was an unmitigated failure, but I don't know how much evidence there is of actual doubt.
