the difference is FT author actually announced that series is only on a break its also confirmed with the re-run of the show,
while in bleach there is no news about the anime whatsoever
It will come back. The 3rd Arc is still only a short way in. Pretty much 1 season tops. This Arc if you were to put it into episodes is going to be about 6 years (6-8 seasons long give or take if he runs a couple seasons in the same year). Its also the second longest Arc, with the First obviously the longest. they just ended the Fullbringers Arc in January this year so i'd say Kubo wants a good amount of time in the manga first, maybe a few seasons a head of schedule then he will start the anime series up again. The first Arc if i recall, had quite a few mid season hiatus's/breaks and a few time we had a nearly full year gap between seasons because the anime caught up too close to the manga. Hopefully we will get less lame fillers
