If we calculate it, we won't get the Tobi unmasking episode 'til the end of the year. As we all know, the next 3 episodes (the episodes left in September,
The Promise of Victory,
Eyes That See Darkness and
Will of Stone) will cover only 1 manga chapters, from 573 to 575. Which means that we have 24 (!!!) chapters before Tobi's unmasking. If we believe that we won't have any fillers until the end of Volume 63 (which is unlikely in my opinion), and from October the episodes continue with their original 2-chapter covering, the Tobi's unmasking will be 12 episodes after 332, which means early January, Shippuuden episode 344. That's what you got when you calculate it, the first episode of January, if there are 4 episodes monthly (October, November and December) before that, though I'm not sure if it won't be shown in the last episode of the year.
