Read about this last night while lurking on NeoGAF. Some folks have pointed out that while this wouldn't be surprising to come from North Korea, this report could potentially just be propaganda from South Korea.
In any case, I don't think the political system in North Korea is going to be around for too much longer. It just sounds like everything is on the verge of falling apart and probably will within the next decade or so. What really scares me is what might happen along the way to that and who might potentially fill the void that Jong-un will leave.
