Filler is needed, no matter how much you don't want it, about 2 and a half manga's make an anime episode, and both are releases weekly, considering how close Bleach is to the manga, i'd say they'd catch up in about 6 episodes.
And anyway, bleach has always had good fillers, some of them started to drag on, but it was all good unique stuff, not just "when someone is thinking of me, thats the place i should return to" repeated 400 times.
You should embrace the filler, the way i see it, it's making the anime last longer, and i don't really want bleach to end =]
