I hope they do that.
And fillers are not so bad if the extend the manga were it's useful, like it is here.
I didn't like that Kishi had Lee, Neji and TenTen around and didn't show them fight, in the manga.
They did nothing in the Kisame fight and he didn't draw the fights against their clones.
That's not so bad if he gave them some fights later on, but he didn't up till now.
So I hope the anime fill(er)s that hole.
