Has the potential to but I'd never bet a system will sell that high this early in it's life. The most I'd be willing to bet at the moment is PS5 will sell at least 100m.

there's no telling, too soon to talk about Ps5 final numbers. PS5 can become Sony best selling console ever above 160M or can end up delivering low sales at something under 50M... only time will tell.

Probably a bit above 100 million it should be considered a failure otherwise.

I feel its dependent on whether or not Microsoft can get more of a good foothold this gen. The more successful Microsoft is the less successful the ps5 will likely be.

I think this depends on the Switch more than it depends on the PS5. Nintendo is expecting 24M units for this FY, meaning that by March 2022 Switch should be at 108.8M units. If FY 2022 is at least 20M, then Switch still has a chance at approaching Nintendo DS and PS2 (though I really don't think it's going to get to quite 155M). If there are significant drops (e.g. "THE CLIFF!"), then it wont. 

If it gets near Nintendo DS and PS2, then PS5 has VERY little chance at having sales as good. Sony has a VERY good track record with their home consoles. Everything but the PS3 has crossed the 100M mark. So maybe crossing 100M is easy for Sony, but crossing 120M, 130M, and 140M is no easy feat. Add this to greater competition, likely less overall exclusive third party games (I'm sure MS will be stepping in for a piece of the pie more), I just don't see the PS5 doing PS2/DS numbers. 

I guess I didn't see Switch getting close to these numbers either. 

It's really hard to say. We have such a normalcy bias. If things stay the way they are in the world or start to go back to the way things were in 2019 and earlier than I am sure that the PS5 will have a very fruitful life and will probably be very close to what the Switch is going to end up at. That said, if the supply chain shortages, chip shortages, cyber attacks and general rise of western authoritarianism and civil unrest continues to escalate the way it has for the past 1.5 years, then I am not sure what that will mean for console sales as a part of the broader economy. I think that the probability of a major political/socio-economic disruption occurring over the next couple of years that could (among many other things) bring console sales to a near stand-still in one or all of the main consumer regions for video game consoles is around 50% in my view. If this happens, the Switch will almost certainly end up being far ahead of the PS5 just by the fact that it was able to develop its install base earlier in time. Of course, I hope that none of this happens, but if you connect the dots of where we are now vs where we were 2 years ago, 2 more years into the future puts us in a pretty dark place.

Hard to say, without knowing when the Super Switch 2 launches. Really I don't see what it matters. Switch was a success and the ps5 will be as well.

Switch will hit number two behind PS2 and PS5 will come third. Seems like a good shout to me.

Although I predict a lot of people may just build budget/mid range PC's now. Would not surprise me if the PS5 sales slow a lot come the next couple of years.

As you wish. I am thinking more like 125-130m. But I will breakdown 130m.

Switch: 130m

Japan- 29m

Americas- 51m

Europe- 33.5m

Others- 16.5m

Yearly Breakdown as of Septermber 30.

2021- 92.86m

2022-112m

2023- 122m

2024- 126m

2025 and etc.- 130m

Switch should have another good year next year with no successor announced and good SW support, ~20m. Beyond that I am not sure how the years will go, but here is a tentative prediction.
