So, weeks or months without Naruto are better than a filler arc like the current one where you would never even know it isn't in the manga if you didn't read it?
Seriously, what kind of "fan" are you people if you don't appreciate all this extra intel on one of the manga's central characters?
And I highly doubt the animation quality would improve otherwise. That's just nonsense.
What is canon?
Is 361 canon?
no, but it sounds like it should be the last episode, because I don't know how they can continue this arc after Kakashi meets team 7...
Yeah they can just retell the entire story all over again but from Kakashi's perspective. Brace yourselves for ten straight years of fillers, and probably more because they might decide to cover the timeskip where Kakashi discovers the Mangekyo and goes on a journey to discover its mysteries.
I'd watch the shit out of that.
Imagine the episode where he's in Itachi's genjutsu for 3 days. Ouch.
During that period he might try to cope with the torture by reminiscing about the days that brought him to where he is up to that point.
Any chance they'll make anime end at roughly the same time as manga? A la FMA.
