I'll say this right now: this had better be something for Switch, or I won't be interested. These Mini Consoles hold zero appeal for me at all. Whether through a subscription or piecemeal purchases, I want these games available digitally on my Switch. If I wanted a hundred different Nintendo systems hooked up under my TV, I may as well as get an actual GameCube and have the whole library. I don't see the appeal of the Classic Consoles at all outside of nostalgia, and even then, that would probably be better served just with the original system.
That said, Nintendo has already said VC is dead and that all we can expect from the Online Service is NES games for the time being, so I'm not getting my hopes up just yet.
