Switch vs Xbox One – VGChartz Gap Charts – October 2019

Switch Vs. Xbox One Global:

Gap change in latest month: 1,099,911 – Switch

Gap change over last 12 months: 13,546,904 - Switch

Total Lead: 2,899,462 – Xbox One

Switch Total Sales: 40,736,064

Xbox One Total Sales: 43,635,526

These graphs are very interesting with each of the consoles passing each other as holiday seasons come for each of them. So far at the points where the comparison is the fairest (12 months and 24 months in) the Switch has been ahead and it should continue for 36 months as well.

Do you do a launch align graph for this one? Or would it be just cruel?

No point in doing a launch align for Switch vs Xbox One. Especially with the Switch about to surpass the Xbox One lifetime sales.

Other interesting records are the Switch surpassing the SNES soon and the PS4 about to surpass the PS1.  No way to do graphs with those as we don't have weekly or monthly worldwide sales for them. 

Whoa @ the gap closing by over a million in October alone.

So unless my maths is off, Xbone has sold about 15 million systems since the Switch launched, during which time Switch has sold 41 million. So almost a 3:1 ratio on average.

And that's despite Xbone having better graphics, all the big AAA multiplats, mutlimedia support, all the things people said that the lack of would cripple the Switch.

That will be the story in the coming years. Switch's predicted outcomes will have moved from the console that will make Nintendo go third party to the console that will become the best-selling one of all time.

Switch vs 3DS and Wii U – VGChartz Gap Charts – October 2019

Switch Vs. 3DS and Wii U Global:

Gap change in latest month: 497,401 – 3DS and Wii U

Gap change over last 12 months: 2,040,880 – Switch

Total Lead: 3,177,933 – 3DS and Wii U

Switch Total Sales: 40,736,064

Switch was actually performing its worst exactly 12 months ago (comparison wise) which was month 20.  Then it gained a lot of ground during months 21 and 22.  Now go back 24 months to month 8.  Switch lost ground 2 years ago going into the holidays (months 9 and 10).

This is because the 3DS was extremely front loaded.  It got a huge price cut in less than a year's time.  So while 3DS + Wii U seems like it's doing better against Switch, it's only because, combined, they shot ahead quickly.  Switch gained ground 12 months ago and it's total should even shoot ahead of 3DS + Wii U after this holiday season.  

In reality Switch has a very different sales curve than 3DS + Wii U, and that is because it is appealing to a much wider audience.  Switch sales are still accelerating, while 3DS + Wii U is decelerating during the corresponding point in time.  12 months from now that Gap Chart is going to look extremely different and this time in Switch's favor.

I do agree with this. The Switch in November and December is going to take the lead and never look back. The Switch is already roughly at half lifetime sales of the 3DS + Wii U.

Yeah Wii U won't contribute much from this point on, and unless I'm mistaken 3DS is nearing the end of its peak.
These coming holidays should close the gap quite a bit.
