Mobile gaming will never cut into the Switch 2's market. 

“Over 250mil” is a rather bold prediction lol. I wonder who those two voters are?

Reviewtechusa fell off hard. How could he make a video with a straight face with the topic being "Switch 2 is all but dead".

People might think hes just trying to click bait or troll but hes absolutely serious, while partially it might be done to click bait, I just think he has an awfully cynical and melodramatic way of thinking about everything.

Keeps bringing up that same stupid point that handheld gaming PCs are taking away the Switch 2's market share in the same sentence where he mentioned "Steam Deck sold 4 Million". Literally i think you can combine every PC handheld in existence during the Switch's life and they probably wouldn't even reach 1/10th of the Switch 1's lifetime sales of 153 Million, it's an awful point that he needs to stop making, most people dont even know what a Steam Deck is or care to know, they just want to play simple fun Nintendo exclusives and many would rather even play 3rd party games with the simplicity of console like the Switch 2.

Says that Switch 2 being easy to get rn is a sign that demand isn't high, OR it could be that Nintendo heavily prepared themselves with stock this time around since it was clear from the beginning Switch 2 will be high in demand. Japan sales numbers are still high, of course sales numbers gonna go down from launch period thats not a point of concern.

How can the fastest selling console of all time be all but dead, insane.... gonna be funny to laugh at this video once Switch 2 easily surpasses 100M again.

Yeah PC handhelds are too niche to have any significant impact on Switch 2; they appeal to the most hardcore enthusiasts, the kind of person who either wouldn't buy a Switch 2 anyway, or who would probably get one in addition to their ROG Ally or Steam Deck.

Switch also has a very different value proposition to phone gaming, people aren't going to opt against getting a Switch 2 just cos they can play candy crush on their phone, if they did Switch 1 wouldn't have been so successful.

PC "handhelds" are not the only one's that will try to make that blue ocean more red.

As for phones - well, they've already shattered once dedicated handheld market - honestly, from my POV, I don't see Switch, PC and future XBOX/PS dedicated "handhelds" as classic handhelds - given their dimensions and weight, it's more sensible to call them portables. Handhelds, as they once were, as in devices you can carry around in your pocket, currently live in smartphones.
And yes, currently, bar the time you spend playing in each category, there is not that much overlap between mobile and dedicated gaming portables market, apart from small collection of titles that are available on both and mobile titles that are aiming to be full-blown console gaming experiences...but for some reason, I have this itch that says that this will all change in next XYZ years.

Phones and hybrids are quite different niches; around the time Switch 1 came out a lot of people predicted that the prevalence of phone gaming would limit its sales as a portable device, yet it still went on to become one of the highest selling systems of all time.

I don't see any reason that would change this time around, attempts to bring console type gaming to phones have failed miserably, the audiences are after two very different things.

Sure, they are different...and there will always be fair amount of separation. Yet, I think that the overlap will become bigger as time goes on. Whether it's through MS pushing for Windows on ARM, VALVE being more aggressive with SteamOS, or via streaming (have you tried GeForce NOW lately? - it's actually mind blowing that you can play even with mouse+kb comfortably, let alone with gamepad). Especially this last one  - there is point in future where for a lot (if not most) people it is just more convenient to have their libraries be accessible from any device, even if at home they have their main device they prefer to play on.

This is not just Switch related, and might not even influence NS2 for better part of its lifecycle, but it's coming, for all, whether we like it or not.
