Yeah so theres my totally inaccurate list.
Only 2 things I really dont like about it are Yoshi being the only Q1 game I listed and no 3rd party partnered game a la Mario + Rabbids or Fire Emblem Warriors. I guess leaving Retro off for another year may not be the smartest either but I wouldnt put it past them
Edit: Oh and no Pikmin 4 but that can be a 2019 game too I guess.
