It's possible his bankai can't be stolen because of they way he obtained it. I don't think anybody has brought this up yet, but think about it. Ichigo and Kisuke are the only ones who have achieved bankai this way and everyone who has used bankai and gotten it stolen has achieved bankai the normal way. Now because Kisuke has never used his, we can't say one way or the other until the real reason is explained, but I just had this thought and felt I should share.

Also, that would probably include Kisuke on the war potentials as well if I'm right. So far that gives us: Ichigo, Kenpachi and Kisuke as war potentials. But that's only if I'm right.
