According to my calculations, for the Switch to hit the 30 Million sold mark for 2020, the Switch needs to be up at least 35% YoY for the next 7 weeks. That is probable to happen imo, the Switch is up around 48% in the first week of November.

It all comes down on the stocks. If Nintendo has enough units at hand, they'll sell them.

Week 45 Breakdown:

PlayStation 4: Down in all regions
Xbox One: Down in all regions
Nintendo Switch: Up in all regions

Week 45 numbers have just been posted. Along with some more adjustments in light of NPD numbers being released. I also noticed some errors in discrepancies with the math that I had to go in and fix.

We are now OFFICIALLY in the holiday season! One week before the launch of the PS5 and Xbox Series.

Moving forward to the end of the year, I will be posting calculations every week. So...

2019 Percentages:
PlayStation 4 - 70.12279654%
Xbox One - 50.62782235%
Nintendo Switch - 59.98396642%

2020 Estimated Final Totals:
PlayStation 4 - 11,187,877 units
Xbox One - 4,751,301 units
Nintendo Switch - 34,153,757 units

Just for the fun of it Imma predict the total sales of the Switch by fiscal year and come up with a total sales prediction in the end.

I will also make a list showing the percent chance the Switch has of outselling each console.

2017 FY: 2.74M

2018 FY: 15.05M

2019 FY: 16.95M

2020 FY: 21.03M

2021 FY: 30M

2022 FY: 25M

2023FY:18M

2024FY:9M

2025FY:5M

2026FY:3M

2027FY:1M

My Total sales prediction: 146.77M Units Sold, the 3rd greatest selling console of all time.

Chance it outsells each console:

3DS 76M: 100%

GBA 81M: 100%

PSP 81M: 100%

Xbox 360 85M: 100%

PS3 87M: 100%

Wii 101M: 100%

PS1 102M: 100%

Gameboy 118M: 80%

PS4 114M+: 60%

Nintendo DS 154M: 15%

PS2 160M: 15%

Haters after the Switch sells 120M+ consoles and sales drop to 18M a year: "I told ya'll that cliff is coming and it killed the Switch" XD

Agreed, while his constant stealth trolling got really boring back in 2017-2018 it would be absolutely hilarious to see how he'd try to twist things to deny Switch's dominance nowadays. 

My guess is right now we'd be at "Switch is only up cos of COVID and no competition, once PS5 is out and the pandemic slows down its sales will fall off a cliff."

Week 46 Breakdown:

PlayStation 4: Down in all regions

Xbox One: Down in all regions

Nintendo Switch: Up in the United States, Europe and the Rest of the World; Down in Japan.

After waiting an extra week, the time has come at last. NEXT GEN IS HERE! The PlayStation 5 and Xbox Series have arrived! And now we get to see them take full effect over the sales and performances of their predecessors. And as we can see, they are having QUITE the effect.

First and foremest, adjustments were made. Xbox One was adjusted just barely up. The PS4 was adjusted notably down. The Nintendo Switch remains unchanged. With that, these are the updated estimates. Furthermore, the Nintendo Switch has now sold over 20 MILLION UNITS for the calendar year with just 6 weeks to go. It managed to do it two weeks before Black Friday. 

Through Week 46, the PS4, Xbox One, and Nintendo Switch sold through these estimated totals of their 2019 finals:

PlayStation 4: 72.42185523%

Xbox One: 52,21720426%

Nintendo Switch: 60.99058445%

If those percentages held, this would be the estimated 2020 finals.

PlayStation 4: 10,796,262 units

Xbox One: 4,678,665 units

Nintendo Switch: 33,654,177 units

Is it true Xbox sold less than 5 million last year? Kinda hard to believe..?

A few months ago Switch had these huge projections based on last year like 33M+, and they seemed like unreal calculations.  Now we are well into November and Switch is still projecting 33M+.  At this point, I'd have to say that if Nintendo can ship enough then they can exceed 30M, especially if they ship these systems to the regions where Switch is in highest demand.  For the rest of the year we're just going to have to sit back and see how much Nintendo can really ship.
