Reaching 100 million units is basically a major milestone for every manufacturer. Even though the Switch will reach the 80-90 million units with ease, all units are a completely different game after that.
There is as much as little evidence that the PS4 could reach 130-150 million units. Let the price drop to 199 dollars, along with bundles with Tsushima, Cyberpunk, FF or TLOU2, and the PS5 could have a much better year than the 10 million units predicted.
Personally, in my opinion, only the PS5 has the most likely chance of trumping the PS2.
