7 months of fillers? This has to be a joke, I doubt even SP are that desperate.
Usually when the opening has spoilers, that's what we get in the anime.
Last opening had Naruto and Sasuke revived, Sage of six paths and his sons and finally, the IT moon. The canon ended with IT activated and then fillers.
This opening does have one spoiler, and that's it. So we may have one episode of canon on March 31st about Madara being defeated.
Also, SP broke a new record regarding filler arcs,

so after that filler arc is done, there is a high chance we will go back to IT fillers.
SP did a 20 episode filler arc this year (Shippuden Chunin exams), that lasted January 8th to May 21st, that was almost half of the year.
