Hello!
You'll get Metroid for sure in 2018, Kirby, Yoshi and maybe Pokemon but I'm not sure about Smash... There has not been one generation with 2 Smash games and I think Sakurai won't be fine with Nintendo doing a port of Smash 4... I think Smash 5 will be something they announce in 2018 and launch in 2019 or 2019-2020.
