My turn for a crack theory; what if the Oken is actually inside Yama-jii? It's been stated that he is the only one who knows where it is, and what better way to protect something that important than to have it so you have to die for anyone to get it?

Aizen's Bankai...hmmm. What Blaze suggested could be feasible ie complete control rather than subtle prodding; it fits the usual 'extension' of abilities from Shikai to Bankai. It's better than real illusions (so reality manipulation, then?) that I've seen in some quarters. But yes, him getting the Oken and all that follows that would wipe out a lot of space for the development of lesser characters. So yes, I expect we'll see his Bankai before the end, but not for a good while yet.

One more thing (another crack theory). We've seen Toshiro get sliced and diced, right? He's activated Bankai again since last time he used Ice Clone. Is it possible that he's used that to pull another fast one?
