A successor for the Switch will not be coming out that soon (if it was a failure maybe).  Switch will be the main hardware line until at least March 2024.

That doesn't make sense, given the context. Wii had like 3 years of insane sales because of its blue ocean strategy - meaning tens of millions of systems were bought by non-gamers, who then only bought a few titles, and that non-gamer market lost interest after a few years once motion controls were no longer some flashy novel thing, so the Wii's sales dropped pretty dramatically at that point, as the PS360 finally got down to reasonable prices. That isn't remotely what is going on today with the Switch. Wii and Switch are not comparable at all, any glance at game sales will tell you as much.

What's the current Switch sales to date now?  I might be losing it xD

By 2024 the industry has already been moved on to new tech. We have already 2 gens showing us this.

Nintendo is comfortable enough by now having a ton of support, releasing third party games and ports between their own first party tittles, avoinding as possible the droughts. Even Nintendo has mentioned, proudly, the amount of games that the Switch is gathering.

They are not after the same tech race between MS and Sony, but after the games that the industry is producing, and having modern tech that allows those developers to port their titles.

By holiday 2022 it would have an almost-6 years life span. DS lasted from holiday 2004 to February 2011 (6 years+3 months) and its Nintendo's most succesful hardware ever.

Also, nobody is saying that the console is going to be discointinued or that it wouldn't get anymore games. I would like to also read why do you believe that Nintendo is going to hold on the Switch until March 2024, and I mean honestly. Maybe I'm missing something.

Current sell through estimate according to VGC is 59.3m the upcoming Q1 report will be a case of shipments being sold as of the end of June as we know of the stock issues in stores but going by VGC's estimate until the Q1 report the NS will be at like 64m come the end of September if they have a very slow quarter current pace though has a possible 66m mark by then, in the holiday period Nintendo averages about 10m in that quarter which means shipments of at least mid to high 70m by the end of this year.

That means the platform next year would only need around 15m to cross the 90m barrier it may hit this mark in September under its current pace.

Switch already leads the 3DS by 16M, and advantage that is growing very fast. By end of the Year the Switch should lead by about 25M and come very close to the 3DS's total sales figures.

The reason why the 3DS crashed and burned so early was because it needed a massive pricecut to get off the ground, which in turn meant that Nintendo didn't have much leverage left in terms of pricecuts later down the road. The 3DS still got cheaper, but the differences were so small that it was barely felt by the consumers and thus had very limited effect, just enough for making sure the sales numbers didn't drop too fast. These are all things that are not true for the Switch.

The 2DS was hideous and lacked the additional power of the then-already released New 3DS. Of course it didn't do well like that. Had Nintendo released the new 2DS XL alongside or shortly after the new 3DS XL and not bothered with the original 2DS, I'm pretty sure it could have had much more of an impact on the 3DS sales than it did.

GC pricecut didn't work because at the time Nintendo still tried to compete with Sony head-on, and against the PS2 at that. That simply couldn't work with the image it had despite doing everything they could to change the image by buying exclusivity deals with many mature games, only for them to rather pay the fine for breach of contract than to linger around on the unsuccessful Gamecube.

Long story short, you just can't compare their situation with pricecuts to the one the Switch is in.

Not just that, Nintendo has actually increased production by 10% to try and meet demand.

The reason it's out of stock is not lower production, but simply very high sales. It's selling at over 300k weekly since early March, at a rate almost no other console has managed to do before. It even mostly keeps up with the best years of the DS in 1H console sales, a feat practically no other console even comes close to achieve.

Or to give you a bit more perspective, Switch sold so for this year as much as it did last year until early November last year - and that year it sold over 19M consoles. And it will pass the 60M sold consoles mark this month and 70M way before the end of this year.

Switch has already overtaken PS4 despite the extra holiday advantage.

Those who doubt Nintendo can have longer legs than Sony are about to learn a lesson as Nintendo sets another new record breaking precedent for the gaming industry.

Almost.
Switch 125M vs 130M PS4

in 2014, 3DS has shipped 7.5 million. (the fourth year of life)
The Switch will probabily ship more than x3 that in 2020. (>22.5m)

Isn't it funny how people still insist to compare the 2 systems.
