The cumulative/total sales for Wii 2012 seem to be missing here, but VGC says it sold 5.1m; I would expect the Switch to beat that since it looks like it will have the first half of the year or so to itself before it's replaced.
3DS is trickier, as it was much cheaper than Switch at the time and the Switch wasn't BC with its games, so it remained a viable impulse purchase through 2017. If Switch 2 is like $450 or more or the current system gets a price reduction then I can see Switch 2025 taking this.
DS is probably out of reach as it was also dirt cheap at the time.
