Even if consoles become more affordable again in the USA and a lot of major regions as a whole, 150 million and up, and especially 200 million (way past PS2) is so unlikely.
I'd put the odds of outselling DS as maybe 10% or so of happening for current or future hardware. And that's generous. 200 million units or more for a console? Maybe a 1% chance, and that's rounding to a whole number. It's probably more like 0.5-0.6% chance.
Consoles still have a place right now, but PC and mobile continue to eat away at them.
Nintendo is very likely to be the last one standing, given their rejection of PC and the types of simple games and apps they put on mobile.
Switch 2 could crack 150 million units or so (a little short of DS and Switch) if it really delivers the games enough for the masses and especially if takes over 8 years to be replaced.
PS5's best hope to crack 150 million units or more is PS6 launching around 2029 or later with PS5 at a more affordable price than right now.
Project Helix can surprise us I'm sure, but is it going to outsell even Xbox Series? I'm skeptical.
