I think its both.
Bomberman was there at launch, before this FY, so its launch month (500k) has to be deducted . Even then, Konami said at the end of march 2018 that bomberman was "approaching" 1M, not actually reaching it yet.
Bomberman R reached the million in March. http://www.topesko.com/2018/03/super-bomberman-r-broke-one-million.html
You know it deserves the GOTY.
