It is possible the Switch's successor is announced not that long before launch but the PS5 doesn't really support your argument since while it was fully shown off in June 2020 it was announced and talked about quite a bit in 2019 so anyone paying a bit of attention knew well in advance the PS5 was coming late 2020.

Switch doesn't support the argument either, because its codename was announced in March 2015 and it was easy enough to figure that a 2016 launch was targeted due to the sales levels of the 3DS and Wii U. Furthermore, in April 2016 Nintendo confirmed that the launch was going to happen in March 2017.

I didn't remember those details off the top of my head but yeah neither support it. Nintendo might announce it not far from launch but with historical precedence it definitely can't be expected.
