User blog comment:Caesarea37/Aizen and the current state of his Zanpakutō/@comment-1393830-20130319190356/@comment-1393830-20130319193009

As of right now, he has no Zanpakuto. He is in a unique position that its not that his Zanpakuto is broken, but rather that it no longer exists, due to the Hogyoku. I'd put money down on him regaining his Zanpakuto during this arc, though there is no telling right now.
