OP didn't mention biggest reason why Splatoon moved more console DK, because Splatoon is far more mass appealing game than DK.
Basically it would be similar like saying why Smash Bros. or Mario Kart moved more consoles than DK. People need to understand that DK is just another 2D Wii U game while Splatoon is great new IP that become third huge IP alongside with MK and Smash, and becoming even more popular IP than Smash.
