Its two predecessors sold 89.5 million units combined according to Nintendo, (13.56 + 75.94) so as of the latest weekly numbers, Switch has outsold them both.

Early in the Switch's life is was often argued by some that because it was replacing them both, it would have to sell better than both to be a success. This number was also often held up as the maximum potential audience for Switch, as the sum total of their previous home console and handheld install base.

Well, here we are.

Now when will it outsell the Wii and Gamecube combined

Now when will it outsell the Wii twice over.

The Switch isn't officially a success before it outsells every previous Nintendo console combined. 

@Leynos Probably by the end of next year.

Forget that!

When will switch outsell NES + SNES + N64 + GC + Wii + Wii U.

VGC will never be satisfied, EVER!!! The cliff is always there

The Switch isn't a success unless every person on Earth has one.

I recall seeing arguments from people that it in fact has to outsell DS and Wii since that was Nintendo's peak...

I'd say Wii U + 3ds is the minimum a unified device should be able to sell (if it wasn't that popular). Wii + DS would be the maximum if it was the most popular device of all time-level.

I think in the end it will be closer to the first than the second, but still ahead by tens of millions.

One of the next big goals is GBA+GameCube. There's virtually no way it will match or exceed DS+Wii.
