If you were one of those people who still desired to give Nintendo your money in exchange for an NES Classic, well, tough shit.
Nintendo has discontinued the Classic in North America and Japan, despite high demand, failing to remotely meet demand, and, for a little while, seeming like they actually might have wanted you to buy one–in January Reggie Fils-Aimé, President of Nintendo America suggested that more were being produced and demand was going to be met.
It’s almost like Nintendo is an egomaniac, desiring to make everyone want them, and to have the bragging rights that: ‘Yes, everyone wants us!’ But that’s all they want.
They will probably release a betterer version of the Classic with more games, or with SNES games, or something, which will also have high demand, and will likely force those who sprung for the original NES Classic to buy another one to get full functionality in their Nintendo brand emulator. I suspect this because this is very much what they did with the Wii U and the Switch regarding The Legend of Zelda: Breath of the Wild and all future Nintendo IP offerings. (The best version of the new Zelda is on the Switch and no more first-party games will be released for the Wii U–if you want the likes of Splatoon 2, and the fancy, complete Mario Kart 8, you have to buy a Switch–they also did this to a lesser degree with the New 3DS).
And if they do do this, it will work. Because, as the Switch showed: Nintendo can successfully bank on your love of their IP to get you to ignore the fact that they treat their consumers with no small measure of contempt.
