Mario Kart and Splatoon are new games.
They said they were going to continue to support 3DS until... what like 2018? To me that just sounded like BS kind of like how when they said the DS was a third pillar to Nintendo and NOT replacing the GBA... but then I realized that Pokemon could and likely will continue on 3DS a little longer since it'll be easy for them to reuse the assets they already have.They should've saved Pokemon Sun and Moon for this. It looks just like X and Y on 3ds and apparently the frame rate struggles on old 3ds.
Not to sound egotistical, because I'd love her and several other Indies in Smash... but before we get said Indies..
