People are missing the point, most people are upgrading to 4K, in fact you almost cant find a 1080p TV anymore.

Then, GTA5 is from last gen, it doesn't hold up well compared to modern games, gta5 is full of jaggies compared with modern open world games.

Then the ps5/xbox series X will be another big jump, further eliminating jaggies.

By next year, the graphics will be way ahead of the switch, switch will still be great for portable games, but not for full console games as those will look leagues ahead on the main consoles, therefore no one will buy a 720p game on switch if they can have it in 2160p on the main consoles, that's like 9x the pixel count, imagine that, and then the main consoles will have better effects, performance and AA, add to that the switch could have maximum 64gb space on the memory on the SD, the new home consoles can do 100GB on 2 discs (2 discs are way cheaper than a 64gb SD).

The switch is fine for ports and some people might trade graphics for portability, but next gen the difference will be far too massive, I personally think it already is, playing witcher 3 on my xbox X is a huge difference to the switch, its like a completely different game all together, so imagine next gen. 3rd party developers will be forced to leave the switch, unless they want to make exclusive games for it.

So, sales will start to slow a lot next year when people witness next gen graphics.

The switch will be left behind just like the Wii was when the ps4/One released. Graphics were acceptable against the ps3/360, but not acceptable compared to the ps4/One

I bought my new 2DS XL for 90dollars second hand, I had before a 3ds lite that I bought 4  years ago for 60dollars second hand.

With that said, I bought my switch 2 years ago for 190dollars second hand with a case and screen protector and Mario kart, I will never understand why people buy brand new, knowing that many people wont like the product and sell it in mint condition for 70% of the price.

I've seen switches for 150 dollars with games on local classifieds, probably people wanting to upgrade to switch lite, or new switch witch has better battery.

Same with 3DS, Nintendo launched so many models that people who upgrade sold their old models for half price.

The best deal I got was my WiiU 32gb with wii mote and pro controller, and 5 games for 60 dollars

And best of all, by the time I bought it, games were 25% of the original price.

Be a smart buyer. With that said, I will buy ps5 on launch day full price, because I know it will be a success and many new games, looking back at switch, we didn't have any decent game until weeks after when Mario odyssey launched, because the other good games I could play on my wiiU, so for the first 5 or 6 months there was only Odyssey, I never buy a console for 1 single game.

I disagree because the Switch is being bought by two markets at the same time.

The core and casuals buying it for the console. But then you have the handheld crowd that normally buys the 3Ds also buying the Switch. Sure their is some overlap but the Switch is a wild card. Nintendo essentially dissolved its handheld division and all their eggs are in Switch

Eww nobody wants that, that'd be a terrible decision. Also they don't have an underpowered hybrid, what they have is an overpowered portable that can be played hybrid. Saying the Switch is underpowered is just crazy - it can play current console games with some downgraded graphics...and its a portable! In no world is that underpowered. Nobody wants a $400 Nintendo system that competes for the exact same market as Xbox and PS. Nintendo's business excels when they think outside the box and give people what they didn't even know they wanted. The high powered clone console market is full with two competing for that title, while the Nintendo enjoys massive success by choosing an overlapping but slightly different market. You want way better looking Zelda game...wait for the Switch 2, which should be like an overpowered PS4 portable in terms of graphics.

The DS was cheap (the Lite was at any rate), had GBA compatibility, highly portable, and had unique software that was lightning in a bottle.
The Switch could very well sell more than the Wii. If it's really lucky, it will outsell the combined sales of the GB and GBC. But it's not touching the DS (pun intended). I don't see any hardware ever coming close to the DS and PS2, though PS4 has a good chance of being the 3rd-best selling video game platform.

Someone say the Switch isn't underpowered? A downclocked Shield from years ago, deluded.

I would say the same thing. Which is a great achievement already.

The main problem with this argument is that you can compare the DS to the first three years of the PS2 and get a similar story.  

Data has not yet shown when Switch will peak.  If we are going by sales so far this year, Switch has not peaked yet comparing YoY Jan-Feb sales to last year (worldwide).  Data has also not given us an indication yet of what Switch's legs will be like.  Going by data alone is going to give an incomplete picture.

On the other hand we can measure market size.  If you combine all of the handheld gamers and all of the home gamers, then that is a huge potential market for Switch.  It only needs to sell to about 55% of that market in order to beat the DS.  On top of that the home version is actually more popular than the Lite version.  Home gamers are going for Switch in a big way and handheld gamers love it too.  Switch has a lot more growth potential than even the DS had.

That is why saying the Switch can't possibly outsell the DS is calling this way too early.  

As a hybrid it’s fine
