I think this is definitely true. Furthermore since Ichigo's zanpakuto was built in a completely different way than any other shinigami, what if the other basic rules of zanpakuto's are also different? For example Ichigo could theoretically redefine the normal system of releases. Instead of having only two, he could learn a third release, one that was more powerful than bankai. That could be how Ichigo's final powers end up. Using his quincy powers to create the framework for his zanpakuto so he isn't confined to just two releases. He could also use hollow powers to power the new release. Maybe we will finally see a not final "final getsuga tensho" ability with the theoretical third release.
