I doubt it. It should sell very well around PS360PSP numbers, but the problem is Nintendo generally cuts support for their devices by year 5 - 6, and launch their successors.
The Switch is selling great, but it's also selling during an era where gaming adoption continues to grow at its fastest. It also launched with an amazing year 1 of exclusives since Nintendo killed the Wii U (a huge benefit for the Switch, but detrimental to their home console brand). And it has had it's first true holiday sales just 9 - 10 months into its lifecycle to help boost overall year 1 sales exponentially.
That being said the Switch is still a big success for Nintendo, and it's on track to be a great seller for them of around 85m IMO, and outsell 3DS + Wii U. Honestly I want to see a sales chart comparison of Switch vs 3DS+Wii U.
