There's at best only a 5% chance of that happening. PS2 sold so well because it was the successor to the titanic PS1. And it continued to sell very well after the PS3 launched due to the PS3's high price and at times lack of software. The PS2 was $129.99 when the PS3 launched at $499.99 and $599.99. If there's even been a next generation vs. old generation price gap that large, please let me know.
The DS was a lightning in the bottle device as well. Smartphones were almost non-existent in 2004. The DS was an inexpensive portable device with a massive library and a touch screen. It was the first Nintendo device with built-in internet, and it had GBA backwards compatibility.
Switch can and likely will outsell the Wii and PS1. Anything else is a pretty tall order.
