There are simply too many unknowns at the moment. Is the system even a year old yet? Something like a PS4 will most definitely outsell the Wii. But I can only say that because the system is proven well enough, we know how long Sony typically supports their systems, and because it still leads pretty strong in the market. I don’t see a PS5 until at least 2020.
Nintendo is a mixed bag. I think it mostly depends on their approach. Nintendo doesn’t support their home consoles for nearly as long as their handhelds, good example being Wii U vs 3DS. But at the same time the Switch is a combination of the two, so I have no idea which it’ll swing towards. Another big factor is life. How long will the Switch last? The thing is, the Switch isn’t super powerful so its 3rd party will probably slow in the next few years, ports from other consoles -mainly. But thankfully for Nintendo it doesn’t have to rely on 3rd party. So that’s not really a big deal. But by 2020 the system will be starting to show its age. The Gamecube lasted, what? 5-6yrs? The Wii was like about 6yrs, maybe 7? Wii U was a flop so I won’t count it. But assuming it lasts about 6yrs, then it’ll probably stay around till 2022.
Honestly, there’s so much that could go right or wrong before the answer is more clear that I’m just rambling. I think it will safely sell 80million. I don’t know if it’ll outsell the Wii, but it very well may have a chance.
