Source shipments ended in December 2015?

Perdón, yes the PSP sold for 7 years and 5 days (Its 8th year, 5 days into it). PSP sold worldwide in Dec 12th 2004 with the PS Vita selling worldwide in Dec 17th 2011. Does that still make the whole argument invalid?

Yes those are all the times of discontinuation.
WiiU sold a measely 1 units in 2023, I gotta give it to little guy for holding out so long :)
I was specifying that consoles sell past their discontinuation notice, consoles sell past the release of their successor. The Switch is pushing the boundaries for Nintendo on what a console can do, and they will continue to do so.

I have to give to the little guy for standing strong in 2023. But yes the WiiU sold for 5 years (4 years & 7 months).

So if I am understanding correctly, if a console sells over a longer period of time it is deemed as a failure?
So the PS2 is a failure?
+158M is a failure? I see +158M as an absolute win. It doesn't matter how long a console lasts on the market, because win it has stopped producing (we can cap the total), but after production finishes the console still has to sell those last produced products. The final number, and shelf life is when the last console is sold.
Your argument is invalid.

The only console to sell faster than the Switch is the DS. The DS reached 151M in its 8th year (7 years & 4 months).
The PS2 took it 11 years (10 years & 2 months) to sell 150M, so by your standard and I quote
"it doesn't matter if it hits 160million, it won't mean what people think anyways, it happened over a longer period of time, it is a sign of failure, not success

sure if it sold 160 million in 6 or 7 years that would be the best selling of all time, but if it hits is after 8 or 9 years all that means is that [Sony] made us suffer for a long time."
You said it not me.

If its been torturous for you to be gaming with the Switch then stop using the Switch, sell it and don't worry about Nintendo anymore, you obviously think they failed, so why would you want the next console (that will do the same thing, sell for too long).

Im not counting the Wii Mini for there weren't any reliable places to quote, nor was it included in Nintendo's reports.
The Wii sold from Nov 19, 2006 and stopped selling until March 2016

(I may have been using wrong lingo so i'll try to use better wording)
Thats 10 years (more specifically, 9 years and 4 months, which is its 10th year).
The Wii had a lifespan of 9 years and 4 months, its 10th year.
If we include the fact that no units were shipped in Jan-Mar '16, then the Wii lifespan was 9 years 1 month and 12 days (still in its 10th year)

The Wii ended production in Oct 24th 2013, its life cycle is 6 years and 11 moths (its 7th year). If we include the RVL-101 (non-compatible with GCN) that was discontinued on May 2014, its life cycle is now 7 years and 6 months (its 8th year).

You can say it sold for X years, when those years are full, not 7 years and 5 days = 8 years.

7 years and days or even months are still 7 years. If you have 7 years and 10/11 months then we can rounded it out to 8 Years yes, it's close enough, however for just 5 days past it's 7th year to say 8 years is just wrong.

Same goes for the 10 years of the Wii. From Nov 2006 to march 2016 those are 9 years and 4 months, far far long of 10 years. It is way more closer to 9 years than it is to 10. So you can't call 10 years of 9 years and 4 months when the argument was specifically for how many years is the trend of the consoles.

Is that making the argument invalid ? I forget about it in the first place .. What was again about ? Longevity of the consoles ? every console reaching 100M is selling for 10 years ? No, in one of my others posts I have you 4 or 5 examples of consoles selling 10 years (or almost 10) that were far from 100M. There is no correlation between the two other than the coincidence chance which is big, for a successful system to have both good sales and long life.

Different boundaries has been pushed by every 2nd system. (Different types of boundaries of course) It's not something new. Congrats for Switch. The only boundaries I see pushing is something mixed between the Sprint of DS and the marathon of the PS2. Trying to have fast huge sales like DS, and trying to continue to sell like PS2. Guess what. It fell short of both. It won't reach PS2, and it didn't reached the sprint of DS's sales. Lifetime sales of both systems won't be reached either by the System, unless Pricecut of 100$ happens or Switch successor got delayed to 2025, which I don't see hapenning.

About the original argument, the guy is right. Switch is not reaching 8 full years on the market before the successor comes. It is coming before March 2025 (Switch's 8 year anniversary). (8 years or 96 months, not 7 years and 5 days, like you are counting them)

I love coming back to this thread. It always interests me. Would love to see it become #1.
Personally though, I don't even think 150 million is guaranteed. I would love to be wrong though. 160 + just is not happening without serious price cuts. Like many others have stated, I think they are focusing more on profits than units sold. Inflation has been crazy, which has me doubting any price cuts will happen. Also a reason why holiday sales aren't as strong this year.
Anecdotally, most family and friends I know have had to make serious changes to keep up with the cost of living, meaning less disposable income. I really do not think it is exclusive to my social circle.

This is at least how I see it, a console first comes out on lets say march 3rd 2017. It is going through its 1st year of selling. Once it reaches March 3rd 2018 it has completed its 1st year and is now starting to sell for the 2nd year. If it sells to March 4th 2018 and stops production, then its 2nd year was only one day. Was it a successful year, no. But its 2nd year was a day of selling, because that one day is a difference between 1 year and 2 years.
So in regards to Switch successor coming before March 2025, it will arrive in the 8th year of selling (because the 7th year was completed in march 2024).
I hope i made my thought process make some sense. (thats why i also added in the exact times in my post before so people can see)

Every Nintendo console has been pushing what new can be done. The Switch is trying to innovate on many aspects (hybrid, controllers, and more like you mentioned).
Every Playstation console pushes how good of an experience can be achieved. (I think)
Every Microsoft console pushes how many users can we achieve (Subscriptions)

I still hold out hope Nintendo can make the push for +160M.

This was the argument
.             ↓

Garrus states that Nintendo always makes the same mistake, which isnt true. They sell their platforms for as long as they deem is economically in favor of them.
And I was supporting the other side of the argument with information on other consoles on how long they've been produced, and sold for.

I never debated about the sales collapsing in the 8th year, because I don't know what they'll do and can't confirm nor deny that opinion.

And there's the typical Garrus statement.  Was waiting for it. And as before, it's a completely silly statement yet you still say it with the confidence that it means some profound truth about the success of the Switch.  Sales figures are sales figures, regardless of how long a device takes to get there.  

Suffer? Suffer?  Man, you live a very, very charmed life if you think a system being on the market for a year or two longer is "suffering."  I've been a Switch owner since day one, and I can assure you there has been no suffering going on in my house.  I've got far too many games to play on this amazing library and none of the experiences I am having feel like they are causing me pain or even annoyance. You're more than welcome to find your happy place on one of the other systems that won't make you feel the pain you are experiencing waiting for a Switch successor.  I wouldn't want you to have to go to the hospital or something so it is in your best interest to stop torturing yourself. 

150m is on lock; Switch will be at 140m by March 31st coming off of a 15m year with dedicated support from Nintendo through the following fiscal.  I don't see a scenario where the console won't move another 10m lifetime, but depending on what Nintendo does and when Switch 2 launches, it could definitely fizzle out right after that and not make it to DS sales.

Last page, Wii shipped .11m until December 2015.

https://www.nintendo.co.jp/ir/pdf/2016/160427e.pdf

Last page, Wii shipped .11m until March 2016.

It is the same number, so can be concluded Nintendo didn't ship any more units during January- March 2016 Quarter. Nintendo didn't include any Wii shipments in any FY report after that.

It honestly wouldn’t be surprising to see Switch languish in the 150s until like the 2030s or something when it finally edges past PS2. That’s a real possibility here.

140M by March 31st ? I am not so sure. It will get to 135/136M with December. From there Switch made around 800/900k monthly sales the last few months before the holidays. Even with that pace it won't reach 140M it will felt short. However by January I expect Switch to drop to around 150k weekly (remeber that before the holidays Switch last couple of weeks were between 180k and 200k) and with that Switch is making no more than 600k monthly, which in return means that it will sell no more 2M for the first 3 months of 2024. Which it means that If it reaches 136M with December, then it is finishing March with no more than 138M.

And depending on when the successor is announced and launched the 10M till the next March of 2025 from April 2024 are under question as well.
