I try to follow news out of North Korea, but it's pretty slim pickings, as you might imagine. Here is a great article offering a rare inside look. There are two money quotes:

1. "In interviews for this article over many months, western policymakers, Chinese experts, North Korean exiles and human rights activists built up a picture of a tightly knit clan leadership in Pyongyang that is on the verge of collapse."

and 2. "According to exiles, North Korean agents in Beijing and Ulan Bator are frantically selling assets to raise cash — an important sign, says one activist, because 'the secret police can always smell the crisis coming before anybody else'."
