Via Twitter an update:
Hamzah bin Ladin's new audio confirms that Abu Basir Nasir al-Wuhayshi was the "deputy leader of Qa'idat al-Jihad". Also interesting: he mentions some of the Iran-based AQC leaders he studied under and speaks of them as still in prison. They were: Ahmad Hasan Abu al-Khayr, Abu Muhammad al-Misri, Sayf al-'Adl and Sulayman Abu Ghayth.
The author is 'alleyesonjihad', a French student.

Quick research found Sulayman Abu Ghayth has been in US custody since March 2013 (subject of posts here IRRC). Both Abu Muhammad al-Misri and Sayf al-'Adl have been reported to be in Iran via Wiki.
