Your point is almost entirely based on exceptions ("if you have the right console bought at the right moment in the right place with the good controllers, you may able to play the game"). That's a whole different situation from a port of SM3DW on the Switch.
Sorry, what? I proved above that every 3D mario game can be played at least on one different system than the original system (plus PC emulation with a bunch of different controllers), so there is no reason that a proper port of any of these games to Switch should be impossible or improbable.
The basic Switch has all the controls it needs to play any of these games properly: two analog sticks, four shoulder buttons, a lot of front buttons, motion control and even a touchscreen. The only issue for Super Mario Sunshine HD could be the lack of analog triggers, but they could easily fix that: button R for the light squirt and button ZR for the full squirtLast edited by Conina - on 03 February 2019
