Omaeda's family was revealed long ago in a Color bleach chap. I think what Mayuri is doing has something to do with Tosen and considering how he is still respected not to mention his conversion over to the SS(or just to Sajin and Shuhei) before his death, I guess he is doing this behind closed doors as to not have to deal with SS bureaucracy and "morality". I guess when what he makes is revealed, if it is some form of modified Tosen, it will be beyond recognition.

Back to Omaeda, I think he should stop sulking and try to actual train. This maybe do to the fact that I am not impressed at all by his shikai but like Shuhei, he should try a hand at bankai attainment.

As for Bromamura, I think his grandfather is fighting him to see if he is worthy of inheriting the family's secrets. Will it result in the old man's death? Maybe considering that Kubo is killing off the "old guard"(T^T Unohanaaaaaaa!).

Ichigo, I think his powers were in mimicry of his fathers being more a mix of his own and his dad, seeing as he was conceived while Isshin's shinigami powers were in Masaki keeping the hollow in check. Given that Ichigo "inherited" White in some form, I think he inherited Engetsu(what I shall use now as an Umbrella term for Isshin's shinigami powers) as well in the form of Zangetsu. I think he was just running around with second hand versions of his parents powers.

What I am interested in seeing is if Ichigo's zan will be in shikai default mode or will be in a sealed state and if it will be a clunky giant blade as well though I digged the original zangetsu's curved cleaver design.

Hopefully Ouetsu will talk about how he came up with the asauchi and a little of their creation process and what the shinigami were like before he came in with his swords.
