Tekkphreke, when you say the Shiba clan, are you including Ishhin? Also, in terms of the maybees, I think it's pretty much guaranteed the people/groups you mentioned will be in the battle, since even they have a stake in this was regardless of their relationship/attitude the have towards the Soul Society especially since we didn't get a whole lot of elaboration on their Zanpakto's special abilities and at least three have a bankai. Shinji returning to the fight is practically guaranteed since Momo is a skilled kido user and probably knows a fair amount of healing techniques. Kira hasn't been confirmed as dead, and we've seen characters survive much more serious injuries (Quilge having his heart completely destroyed, anyone?), so we can't totally count him as gone for good until we learn one way or another. I personally think that Ryuken will likely join the fight against the Wandenreich, since he has every reason in the world to hate them, with Ywhach being responsible for Masaki and Katagiri's deaths, and, (seemingly) recruiting Uryu, his only remaining family, into their ranks behind his back.
