Maybe its just me, but for some reason, the way ichigo said "I will save you" sounded a bit like when he turned into his second hollow form against ulquiorra... Maybe H Ichigo will get a comeback
I've been thinking, what about uryu? Why are his arrows weaker than Kirge's? I think Uryu has been holding back power, and maybe he has another sword type weapon, like ziele schneide (sorry don't know how to spell it)? in that case that explains Urahara's expression. Although it is a bit far-fetched
I'd say Kenpachi will get beaten by Buckbeard, and old man yama will get weakened, like he was against aizen. It'll all be up to ichigo
