Make note of something about the Bankai's in the series. Out of all the current captains only Soifon, Byakuya, Komamura, Hitsugaya, Mayuri's have been seen. Albeit considering the extreme versatility and potential power of Hitsugaya's we may have only scratched the surface of what they are fully capable of besides what we have seen.

Is it strange that the four oldest and most powerful captain's Yamamoto, Unohana, Shunsui and Ukitake we have not seen any bankai at all. Even more so we have barely seen their shikai or rather have not seen the full capability of their shikai though we have gotten glimpses at best. With what little we have seen of Yamamoto's its destructive over all else but apparently we havent seen everything only at Shikai. The potential capabilities of Shunsui's alone is tremendous. Is it a wonder they have conveniently been taken out of the current arc in some way or another.

Outside of the captains we have the Vizard who seem to be under the same plan. So far we have seen only Kensei's bankai but we have no idea what it does. So far we have seen Shinji, Love, Rose, Kensei, Lisa adn Hiyori's shikai but we have not scratched the surface of their true capabilities, besides Shinji who we fully know. Lisa and Hiyori's werent shown doing anything at all so where still in the dark. Mashiro and Hachi haven't shown anything at all.

Yoruichi has neither shown any Zanpakuto period nor has Tessai. Urahara has shown his shikai and a myriad of abilities though only scratching the potential surface still and no bankai looking to emerge from him anytime soon.

As for the Aizen he has shown the full capability of his shikai, and even if he had used his bankai we would never know. Tosen we saw his shikai and bankai back in the SS arc and along those lines we have also seen the shikai and bankai of Gin (which considering what happened with Tosen it looks like he is the next to go down). The main concept is we have seen all Gin has to offer now so he's as good as gone.
