I very much doubt that...

If PS4 finishes around 110-120m, I think Switch will outsell it.

No joke.

So, in no uncertain terms, you are saying 110 million minimum for the Switch? Maybe if Nintendo has 4-5 Switch revisions to the PS4's 3-4. Nobody ever wants to back their comments up and bet. I'll take the low end of your prediction because I'm so lovely. Switch 110 million not happening for 6 months avi/sig control, and another 6 months for Switch not outselling PS4 in general. A tie is possible if we each win one side of the bet. Non compliance results in a 1 year ban. I usually only call out the most outlandish posts. This is as risky as I get, because this IS possible, but I think it won't happen, and want to have some fun. With your VGC identity. For one year. I don't know how to handle the hardware revision situation, because I feel the Switch could eclipse the PS4 in that area, staying on the market under the same name for a longer period, while Sony clearly moves on to the PS5. I guess I'll just eat that one......Well?

OK, I'm happy to do both.

1. The PC market back was very much separate from the console market unlike today where there is some overlapping. As you yourself pointed out - the markets were very much separate and not in competition with one another.

2. You said MS can only sell in NA and the UK - well that's 2 of the biggest gaming markets right there. They're much bigger competition than Nintendo has ever faced with the NES.

3. You're giving me an article about why the 3DS wasn't selling in 2011 - a year when less than 15% of mobile users had a smartphone. Compare this to 2015 when 77% of mobile users had a smartphone. There's also a big difference between mobile gaming in 2011 vs now.

On top of that, you're ignoring the downwards trend of consoles in Japan. The NES is the 2nd highest selling console in Japan with only the PS2 surpassing it. Even th Wii only sold 12.5M there compared to the NES's 19.35M.

Now, let's look at a point that you forgot: Rise of alternative forms of entertainment. During the NES era, you're at home, you're a kid - what's the best way to spend time - video games. Any other distraction back then is still available today. But now:

1. Social media. The average perso spends 116 minutes, almost 2 hours per day, on social media. That's 2 hours that could have been spent on gaming.

2. Streaming services. It's easy to now access thousands of movies/shows to entertain oneself. Average time spent on just Netflix by a subscriber is 1h33min per day. That's more time that could have been spent gaming.

3. And yes, smartphones. Smartphones cut into people's use of a gaming device and it provides multiple ways to spend time.

All of the above compete against the PS4 in one way or  another as they offer alternative ways to spend time.

When you consider the market difference between 1985 and 2013, it's not really that impressive. It's like comparing revenue for movies and not adjusting for inflation. The NES selling 60 million units in the climate it launched in is like the PS4 selling 300 million units.

I wonder about the future... will there be cyborg scalpers selling them on ebay or will we just have scalp bot vendors on the streets?

On topic though, great milestone :) Ps4 is a monster.
