But yeah, if he's not dead he's probably in a vegetative state. NK is all about demonstrations of strength and such so any rumours that would cast a Kim in a position of weakness would be disproved quickly.

Kim Jong-un hasn't been seen for a reason and that reason is probably that he is dead or close to it.

I assume it must be an assassination or a coup of some sort, the chances of him dying on the operating table (or it being botched that badly that he's basically dead) seems slim to me.
