What do you guys think? I've been seeing some people believe the Switch is in trouble with the PS5 & Xbox SX release. However, I think the Switch will do fine because it's a completely different type of system and stands out enough to people to purchase it as a complementary system with their PS and Xbox's.

First adopters already own the Switch or will never get a Switch, don't see much changing, different niches

How much was DS affected by PS3 or 360?

None. Same deal here.

Two very different segments of the overall gaming audience.
The type of gamers/consumers who will buy a brand new $500-600 console at launch or within the first year are not the same kind of people who wait until year 4-5 of a different system to buy it for $200-300.
They either already have a Switch or never intended to buy one anyway. If the Switch does decline next year, it’ll have more to do with it entering its 5th year on the market with most of its library and big games already out with an install base well over 70 million and nearing the point of saturation.
The PS5/XSX will have very little, if anything at all, to do with it.

Switch sales will not be affected by PS5/XSX.
They're totally different products that overlap rather than directly competing.
This is proven by PS4/Xbone sales not be harmed by the Switch's rise to success.

I suspect there will be some impact. They're not totally different products in the sense that they compete for a similar segment of a household's budget.

Lately Switch sales have benefited from a drop off in PS4/X1 sales, which in turn has occurred in part due to the imminent release of the next gen machines.

I think Switch will not be affected that much by the upcoming consoles. The Switch is barely getting any of the AAA third party games now, so not much will change going into the new gen. Indies are likely to remain supportive of Switch due to the nature of the console, Nintendo’s great support, and the great reception they have from Switch fans, even if there are so many games coming out of the eshop.

Outside of that, the Switch will continue as long as Nintendo provides adequate first party software, which is sorta hard at this time due to the pandemic. But it seems to be working in their favor in a sense as we see from the recent months of sales charts as they can barely provide adequate supply of their hardware (and sometimes software) and they are dominating left and right. Japan is basically Nintendo Land before their actual theme park has even opened yet. Right now, they are probably taking it on the safe side and do not need a January 2013-like direct unless they are ready to show progress of their upcoming titles they know will come sooner than later.

Not to mention, the prices from the upcoming consoles will be relatively high, if rumors and reports are correct. $400-500 consoles will be tough sells for some potential buyers, especially when the US is struggling economically. While we had a recession back in the late 2000s, this is different. People are losing their jobs, struggling to get new jobs as businesses are still struggling to open again, especially as we see an increase in COVID cases recently. If stay-at-home orders extend to a certain point (like Fall), it’s gonna be really tough for the ordinary mom and pop or adult trying to make ends meet to consider buying new hardware for $400-500 with games (not to mention subscriptions, accessories, and the like), even during the holidays. Even Sony said they are planning for a limited launch for the PS5 this holiday.

It won't affect it in a major way. The first couple of weeks it may see a decrease in sales because of early PS5/XBX adopters, but it will pick up right back in no time.

I think at launch, switch will be down when next gen launches, but afterwards it will pick up and be back to what it’s selling. Wasn’t PS4 and Xbox one down when switch launched, and picked up/back to normal once the hype has settled a bit?
