Last week the Army Chief of Staff for six years, General Kiyani announced his retirement; effective on the 29th November 2013, link to his official statement:http://ispr.gov.pk/front/main.asp?o=...date=2013/10/6

FP.com has an optimistic article on the implications, although from this faraway vantage point his successor has quite a lot to do:
The next army chief will have his work cut out for him. In addition to convincing the reluctant civilian government to continue the fight against the Pakistani Taliban, he will have to help manage the Afghanistan endgame as U.S. troops withdraw and a presidential election take place next year.
