Only if the filler arc lasts for over a year, which I doubt...
You cannot use bleach as an example, because the next anime arc is indeed filler for Bleach, thus it is running the same line as Naruto.
I maybe an idiot, but this made no sense to me.
This is to prevent the problem in the long run, which would be to run into the long two year fillers. Think about it this way, if Naruto originally had a 3 year head start, and had to resort to 2 years filler, then we are only roughly 1 year ahead right now and thus in considerable danger of the elongated fillers.
