Here is what happened in the last year since the Obito reveal:
We found out exactly what happened to Obito after Kakashi left him and why he fell to the dark side.
We found out what happened to Madara after his fight with Hashirama (because the rumor was Madara never died but lived on).
We found how how Madara was able to keep himself alive.
We got to see how Hashirama defeated Madara.
We got to see where the Rinnigan eyes came from and it was revealed how they came to be.
We got to see who was in that coffin that Kabuto was threatening Tobi/Obito with.
We found out that Gaara's mom actually loved him and so did his mentor (despite what his mentor did). Basically, we got closure to Gaara's entire story.
Neji was killed.
We found out how Rin died.
Naruto finally mastered his biju.
Naruto mastered all the biju.
Naruto became the most adapt chakra controller in the story, that we know of (the great sage may be better...who knows).
We found out that the Great Sage's mother was the one that started all this shit (why is this not one of the most interesting reveals?).
The old Hokage's were revived and we finally got the whole backstory to Konoha's creation.
We got Madara's backstory.
We got the whole truth to Itachi's backstory.
Sasuke finally got some closure from Itachi (one of the most important plot pieces in the manga). Sasuke is now one of the good guys...we think.
The moon's eye plan was fully revealed and almost happened (we didn't know exactly how it would happen).
The 10-tails was finally reborn and we saw pretty much all of its tricks.
Kakashi and Tobi got closure to their whole ordeal and Tobi tried to redeem himself before Kishimoto decided to cruelly rip that atonement away from Tobi.
And now we know that the plan, the whole time, was to revive Madara (into flesh form) and Madara executes the Moon's Eye plan.
Tons of shit happened. Tons. In fact, more of the story/plot was revealed and resolved in this last year than any previous year. This has been one of the most "revealy" and plot tie-up years in Naruto's history.
