I doubt it'll take the form of a Rogue NK General doing his best Al Haig impression on NKTV, but there are going to be some power struggles. KJI didn't have enough time to cement KJU in place as his successor - 3 years as opposed to the 14 he had before KIS keeled over. Plus, apparently part of the delay was to keep all the factions backing one son or general or another off balance.
But even if there are no power sturggles, the danger then becomes the DPRK trying to start another incident to burnish the "Great Successor"'s credentials or get the other generals to fall in line. The rumor is that was the impetous behind the sinking of the ROK corvette last year and shelling Yeonpyeong Island. The difficulty is that the ROK government is under enormous pressure for not responding to those provocations, and I don't think politically they could afford to let another one slide.
