It seems the North Koreans continue to be committed to the missile program in an attempt to remain a relevant military threat to the US and its allies:
Satellite imagery indicates North Korea has been testing rocket engines, a sign it continues to develop its long-range ballistic missiles, a U.S. academic institute said Monday.
The analysis provided to The Associated Press is based on satellite images taken as recently as late September of the Sohae site on the secretive country’s northwest coast. In April, the North launched a rocket from there in a failed attempt to propel a satellite into space in defiance of a U.N. ban.
The analysis on the website of the U.S.-Korea Institute at Johns Hopkins School of Advanced International Studies, which is called “38 North,” said it remains unclear whether the North is preparing another rocket launch but predicted it may embark on new rocket and nuclear tests in the first half of 2013.

You can read the rest at the link, but since the US Presidential election is over the North Koreans are due to do something next year to raise tensions in order to create a “crisis” that will require the US and its allies to give it free stuff. Firing a new missile over Japan or something similar would be a good way to do this and is actually something they have the capability to do unlike their failed rocket launch earlier this year.
