Is this naruto's final arc? If not, when will it all be over?

It does somehow feel that way, with naruto having achieved a level of power worthy of an Hokage and with the apparently inevitable round 2 with Sasuke.

On the other hand, we still have alot of loose ends with the 8 tails still roaming about, 3 Akatsuki members left and all the mystery surrounding Toby

So how close do you think we are to the end?
