Smash Hero
I mean.Gotta be honest; I have a feeling that the Inklings are a guaranteed lock in for Smash if we ever see the game or the port (depending on which path Nintendo decides to take it).
Them appearing in a brand new game AND the Mario Kart 8 port is evidence enough for me.
Hasn't the consensus largely been "When, not if."?
Splatoon has been the first new IP to make a BIG impact for Nintendo since.... Smash itself? Like, it's far bigger than Pikmin or AC's launches, and yeah, it's carrying that momentum hard into a sequel and crossovers.
It's all of that which made people as "convinced" as they were for DLC/Ballot impact.
