I might be saying this because I can't take Yammi seriously after being humiliated constantly, but with WW in KT, Yammi is the only threat we know of in HM, along with all the captains trapped. I don't see them needing help.. other than getting out. If anything, I bet after next week, he'll have the vizard appear in KT, before he switches back to HM to get us pumped up over it, just to disappoint us with whats going on in HM for the next.. whenever the anime finishes it's possibly lame fillers.

I knew the moment I saw WW he was gonna take someone out, he sensed out the nearest strongest, and went for it. I wasn't expecting it to be so fast though, same with Shunsui getting waxed by Stark. Even though Aizen's out of the fire, I'm still going by his words.. especially now.

As for the hollows, I think they have always been able to enter the real world. Either way from the sounds of it, Stark knows it was Aizen's plan to "speed" things up, so Aizen could of somehow arranged it, even if it wasn't possible. I'm just assuming, that he just closed all the captains entrance/exits, they entered from via Urahara.
