BINGO! 

SW1 has basically kicked off the ecosystem wars, so even if it does eventually surpass PS2, it's only a matter of time before it gets passed, and likely not that long.
With PS6 having a handheld and home console, SNY could totally hit 160M+ if they do things right. Even more possible if they add a 3rd SKU by turning the handheld into a cheap home console.

Or prolong this generation through 2030, and do it with PS5 ? 

They can’t prolong it, they gonna fall behind on tech and end up paying more to have late ps6 manufactured. Best thing to do is lock in manufac cost now for 2027 launch than lock in 2029 manufac cost for a 2030 launch. Then they can add and subtract what they want after but at least the 6 will be on the market competing by 2027.

If they dropped a PS5 handheld in the next year or two, that could allow for a 2030 PS6.

Even if the handheld was designed to be compatible with PS5 and PS6 games, but not marketed as a PS5 or PS6 device specifically, as long as it was launched in the next few years, PS5 could last until 2030 in that case. Problem then is do you count its sales separately even though it's part of the same ecosystem, or possibly 2 ecosystems by splitting gens?

Otherwise I don't see PS5 hitting anywhere near 160M.

I mean, the Switch 2 has been breaking all the sales records. If not the the Switch 1, I would count on it to be the next 160+... But when it cames to the Switch 2, most people people like to cut its legs by saying "hybrid is not a novelty anymore. 120M at most", "It won't pass through a pandemic. 130M at most", "Too expensive. 110M at most"

To add onto this, it still is considered illegal to lie about sales numbers of a product even well after it's been discontinued. It makes sense why, investors don't only care about current sales numbers of supported products, they also care about the company's history to determine if they have a good enough track record to invest, and even sales numbers from discontinued products can influence investing decisions.

While supposedly lying by adding another 5 million to an already high and successful 155 Million sold console thats been discontinued for 13 years from a reputable company & brand like Sony/Playstation is unlikely to be a significant influence for investor decision-making and maybe not enough to raise eyebrows from legal authorities, it would be stupid and unnecessary for Sony to feel so insecure about losing their #1 bestselling console spot for a console that's been discontinued over a decade and does absolutely nothing for their bottom line that theyd risk lying about their sales numbers just to keep that record. If Sony was truly worried about that and was actually making that a priority, I'd be heavily concerned about the company's future if they're that worried about that over making money.

Ya but nobodies worried or losing their minds over SW2 potentially outselling SW1, even if that's after SW1 ever surpasses PS2.

So SW1 can go ahead and sell 155M-165M. Then SW2 can follow with 170M-180M. Then PS6 can follow that with 190M-200M.

The decline of the Switch sales will be determined by the Switch Lite.

It's not the most popular model since launch, but after the Switch2 arrived it's the model that loses the least sales both in absolute and percentage terms. In the end I believe it's the Lite that determines the bottom level of Switch sales in a year or 2 going forward.

I cannot see a possible Switch2 lite anywhere near that $200 price point and I actually believe a 'regular Switch2 excluding dock' would be the next SKU ($380) if Nintendo needs to offer a cheaper alternative in a year or 2.

ohhh i wanna join in....
