I find your lack of Yoshi in the 2019 list quite saddening. :P
Otherwise, I am glad someone has looked at the year somewhat rationally. No one was expecting the Switch to do better than the year that Mario and Zelda released but I don't see why people thought that it would just die off (maybe because of the Wii U...but that was a system that wasn't even supported right from the get go and releases got really sparse for it.). This one started with a great first year and already announced content for this year and 2019.
But do we know if it'll come in 2019 or will it rather follow the way of KHIII?
