Since zaraki defeated unohana, it became easier for him to know the name of his zanpakuto. So maybe he has a chance of achieving bankai. Besides, not always people need 10 years at a stretch to achieve bankai. We've seen that previously in the manga, in time of a dire need a bankai always appeared to save the day. On an opposite case, maybe kubo wants to show us that zaraki kenpachi is so strong that he wouldn't need a bankai to beat the enemy. Only his shikai is enough. Now that would be interesting.
