As Balsalom just said, Ichigo will reach the pinnacle of his powers in this arc. He will probably be much stronger than he was post-Dangai trining. Would SS really let him return to the Human World being that strong? Remember how Hogyoku Aizen affected Keigo and the others? I too don't think he'll become a captain or is suited for it, but I can see how he may not be able to return to the Human World.
