@samurai:
Besides all of the senior captains showing up, i would`t mind Urahara and Isshin coming to hueco mundo to help things up a bit.
I think that's a bit too much. Let's not waste all of the good surprises before the Winter War, eh?
Okay, let's say that Soul Society cleans up the remaining Espada and then peace out. That leaves Old Guy, Grimmjow, Halibel, Yammi, Ulquiorra, Stark, Wonderweiss, and the three former Soul Society captains leading a huge number of hollows into the Winter War.
How in the hell is Aizen going to get stronger men? The Hogyoku is supposed to weaken after continual use. That's why Orihime's there in the first place, to fix the bloody thing. I mean, they're facing overwhelming odds as is (Soul Society, Karakura Town (Urahara and co.), and Vizards v. Espada). It's going to be really interesting to see how Kubo plays out the end of the Las Noches arc and how he evens up the playing field.
I can see either one (or more) of the invading Soul Society captains getting offed or we're about to see Orihime get 'napped soon (Ulquiorra?) in order to serve her purpose for the Bad Guys.
