I personally think that Renji and Byakuya are both strong enough to make a difference at this point. We haven't seen the full extent of either of their new powers either. I don't think the arc is in its closing stages yet, there's going to be something that makes the battle come to a standstill, and everyone is going to regroup for one (real) final confrontation.
