if you mean lifetime sales, it entirely depends on the Switch Lifespan, assuming Nintendo will keep following with the Traditional 5-6 Years Lifespan, on which the Switch successor would release around 2022-23 and the current switch sales would drop after the announcement (similar to how DS sales dropped of cliff following the 3DS announcement in 2010-2011, similar to Wii after Wii U announcement)
as for weekly Sales id Say the PS5 will outsell the Switch around 2022 (again Depends on how longer The Switch Lifespan is)
