Regarding the theme of my post, What I'm trying to say is that there is no "REAL" or "SUBSTANCIAL" difference between the different races of spirit beings. About your question, what I'm saying is that once Ichigo accepted his own sword in his inner world, you could say that there is no more zanpakutoh, nor shinigami, nor hollow, just one being. And the conciousnesses of Zangetsu and Ogichi are not sleeping, they merged with Ichigo, but Ichigo, and most of the Shinigami are so "accostumed" to having a separate entity with them, they consider that if said entity is gone, there is no more power. I think that Isshin recovered his powers, but because of that mental barrier, he thinks that his zanpakutoh is just a lifeless tool which retains the ability, but not the spirit, when the spirit is always with him. Ichigo will probably recover his powers the same way as Isshin, just faster, and will find himself with the same issue of "thinking" that Zangetsu is gone, and only the ability of his zanpakutoh remains, which would explain why Isshin did not use shikai, simply because he still "thinks" that shikai is a "REAL" concept, when it is nothing more than a failed approach to reach the original state zanpakutoh and shinigami have. The physical form of said state is the Sword merged with the hand, just like Aizen said. This might also imply that Tensa Zangetsu was never a bankai in the sense of the word that Byakuya has, but a more succesful approach to the original state, while the sealed and shikai forms are result of the chaotic state Ichigo had at first.
Anyway, once Ichigo finds himself on the need of recovering his powers, he will, but wil mistakenly think that zangetsu is gone. Once Ichigo becomes aware that Zangetsu and himself have merged, that his sword does not answer to him because the spirit of the sword is no longer there, and that he has never been left alone, THEN Ichigo will go back to the Trascended state he reached through the training in Dangai.
Let me put it this way. The sealed form is the best state the zanpakutoh can be in order to merge with the wielder. Shikai and Bankai are the independent approach that the swords take to unleash the whole power, but by being independent, it means that the wielder does not "release" himself. In Ichigo's case, his sealed form was innappropiate for that purpose, and the same his shikai. Against any other example, his bankai, being the "simplest" form possible, was the best form to merge with Ichigo, and the Final Getsuga Tenshou is what to others, would be both the Shinigami and the Zanpakutoh, as one, reaching a true "Bankai" . To summarize: Zanpakutoh in sealed, or more specifically, in its "simplest" form, plus shinigami, who can't evolve by itself
I hope I made things more clear to you.
