So, Splatoon moved more consoles than DK Tropical Freeze

[MrYoshi]

Donkey Kong never was that popular of a game anyways. Maybe it sold more than 6 million on the Wii. But Splatoon on the Wii would've sold probably more than 10.

So does that mean that Splatoon is bigger? Yes.
Does this mean this is the end of Donkey Kong? of course not.
