Kinda like that bit in Dragonball Z where everyone escaped Hell, but they were so pathetic even Krillin could deal with them...

Hey, it means that Chad will have someone he can actually beat up!

That or at some point in the future a new big bad shows up and they release Aizen to help fight him, inevitably leading to him and Ichigo becoming friend/rivals, the Vegeta to Ichigo's Goku (Byakuya and Grimmjow are Piccolo they'll stay useful for a little while, Kenpachi is Tien, everyone else is Yamcha, Bulma or Krillin), but with infinitely more gay undertones.

Hell that lonely sword line already sets it all up.
