Wow I just looked at the totals, I didn't realise Wii crashed so damn hard. I knew it was hard but after all these years it barely made it to 101million. I thought it would have reached around the 110 million with the tail but there is basically no tail lol.

Nintendo needs to maintain and improve the physical storage and 3 in 1 ways of play. 

I don't think things are quite as gloomy for the PS5 as many here suggest.
Yes, its selling poorly at the moment due to supply issues, but with all the pent up demand it could see a huge resurgence once the stock finally becomes available. The chip crunch in its early years may also lead this generation to last longer than usual as Sony/MS try to recoup their early losses.
I don't think it's out of the question that PS5 can still catch up and outsell PS4 by seeing higher peaks than its predecessor ever did.

Passing PS3 is a guarantee, only way that doesn't happen is if the chip crunch never alleviates, and eventually it will.

Agree but they dnt need t do it on the console, they can do it with the carts. and make them writable so you can write updates and patches to them as well as your save files.

I men shit a 64gb flash drive cost me $7 bux. Surely they can get 128gb ones for less than that in bulk production

What yearly sales pace are you expecting? Since it's probably gonna be close to 30m by the end of this year I don't see how it won't sell enough in 2023-2027 to reach 100m unless sales somehow don't notably pick up when stock improves.

I do agree it'll be difficult to reach the PS4 lifetime, at this point I think that's really unlikely. I could potentially see it having peak years as good as the PS4 due to pent up demand but it will have a lower average per year for sure.

Doesn't feel like there's any reason to believe PS5 will fall short of PS3 unless we're assuming the chip supply issue won't resolve itself til the end of the generation.

In regards to passing PS4 which is a tall order, it all depends on what the PS5's peak looks like and how long its on market for. At this point its just a guessing game. Sony remains concerned with getting consoles in people's hands, hence the $399 digital only console so we know they want to get many PS5's out there. What they're not going to do is cut into large profit margins just to hit specific sales milestones (cutting PS4's price just to hit 120m). Now they have their new focus on creating multimedia IPs, that may change their focus on hardware sales for better or for worse.

I'd also assume that later console revision like Slims and Pro will have bigger demand than before because:
1. PS5 is huge.

2. Performance profiles are more common nowadays and people are more familiarised with the benefit of 60fps modes/RT modes/Resolution modes etc.

3. Diminishing returns will lead to a longer generation.

With the way demand is pent up I can see PS5 having insanely high peaks once the chip crunch subsides.
If supply was no obstacle I think it could hit 30 million in a year.
Not only has it inherited the popularity of the PS4, but the fact it's been unobtainable for so long has made it even more desirable and fueled a monstrous amount of hype and an almost mystical quality around it.

This would be a tall order. Most Sony consoles haven't even hit 20M in a single year, and no Sony console has ever hit 30M in a single year. 

The scarcity principle is creating an illusion of unprecedented demand, and I think it is fooling a lot of people. What would likely happen if the chip shortage were to magically go away is that Sony would capitalize on the current demand, that same month would probably have record breaking sales numbers, sales would remain high for a few months, but then demand would begin to settle. This is because scarcity makes people feel a product is better and can even increase their commitment towards buying a product since they "want what they can't have". Then they go searching for it. There are panic buyers, people that purchase products to make money (i.e. scalpers), those that purchase products as a way to assert status, and just general "buzz" around a product that is constantly sold out (Think about the Wii). 

IF the product were to sell 30M in a year, demand would drop pretty fast and the following year would be much lower. In all honesty, even if the chip shortage disappeared I don't think that Sony would plan to make that many PS5's in a year until they found that the demand could be consistent.
