Why wouldn't it ? The Switch's sale numbers path isn't similar to the Wii's.
People bought the Wii for Wii Sports, which led to a massive sale drop once they realised it doesn't do much of this for they were looking for (aka not expensive video games and accessories).
Now people are buying the Switch for Zelda, Mario, Pokémon and many more. And they are buying it for exaclty what it is: a gaming console.
So you are saying switch will be the first gaming system ever to not decline in sales?
It will keep selling 20+ each year?
Some people here think the 100mill mark is easy to do.
