Switch vs Wii – VGChartz Gap Charts – October 2019
Switch Vs. Wii Global:
Gap change in latest month: 408,110 - NS
Gap change over last 12 months: 2,230,955 - Wii
Total Lead: 9,689,903 - Wii
Switch Total Sales: 40,736,064
Wii Total Sales: 50,425,967
I'm still of the opinion that Switch can (and will, unless Nintendo stupidly cut it short prematurely) catch up and outsell the Wii eventually.
Wii got 4 years of support, then was abandoned overnight. Unless the make the same mistake again, Switch can last longer and leg it to victory.
PS4 fell behind quickly and in the end was able to outsell the Wii. Switch has been keeping up with PS4 sales when you align the launches. Switch Lite could push sales above the PS4. But either way I'd say the Switch will likely catch up to the Wii after 5~ years.
