This entire arc seems meaningless, except to give Ichigo his powers back...and we all knew that was going to happen anyway.
Also, why are they suddenly viewed as SUCH a threat? Ginjo MAYBE, but isn't Ichigo still supposedly at a level unheard of? He beat Aizen, for cryin' out loud. Also, the power that was given to the others? That *fraction* of his real power? Wouldn't that not be enough to make such a huge difference?
"Hey, we all got a tiny bit of Ichigo's power! YEAH!"

Suddenly, deads.
