Lmao what the heck is this? 

You can easily switch this to Wii vs PS3, DS vs PSP, and Vita vs 3DS and have different outcomes. 

This.  People are constantly overestimating Nintendo's legs for their consoles, while underestimating Sony's.  I also remember the people who said the PS4 was never going to beat the Wii, even though 2 out of 3 of Sony's previous systems did.  And the one that didn't came in a pretty close 2nd in that same gen with the Wii, 101.6M vs 87.4M.  And that was the gen they utterly screwed up.  Then, we had it won't hit 110M, which it will by the end of this quarter.  And now, it's "it won't hit 120M," even though it is a mere 12M away from that number, now. 

Now, I can definitely see Switch hitting 100M, give or take 10M.  But, it's not going to hit 125M, like the PS4 will most likely do.  I mean, the PS4 looks to be on track to sell 120M even without a price cut.  Give it one or two more, I can definitely see it hitting 125M-130M. 

I would just like to know what is going to keep the Switch selling ~20M every year for the next 4 years to get it to that number.  By 2021, all of Nintendo's big hitters will be out.  It will be receiving fewer AA and AAA ports thanks to those teams focusing on the newer systems.  Speaking of which, the novelty of being the new toy on the block will have completely worn off, as well.  And it will have already had a $199 SKU for over a year, pushing sales for those not willing to pay $299, so a price cut will have less of an impact by then than it would for the PS4.

I think the same, but I see the next 9th gen hybrid system of Nintendo (a sort of Switch but with the power of a PS4(Pro)), for Nov 2022 instead, which let a comfortable room for a Switch Pro this year running games at higher resolution and framerate, but it will be still quite far from base X1 and PS4 in term of power.

You're comparing consoles that weren't in the same generation to fit some odd narrative. I guess if it entertains you... 

Is there a Nintendo console that didn't die hard in its last years?

You have a lot of explanning to do on why you think sales drop to 0 when a successor releases. And following that logic, why you don't expect the ps4 to stop selling the moment ps5 shows up. I expect the switch to be over 110m by dec 31 2022 and it won't magically stop selling because it's successor just came out.

That doesn't make sense to me. Why does Switch get its own gen? With that logic Switch 2 will need to be in gen 11 by itself. Did Dreamcast get a gen all to itself?

Switch is still part of gen 8. It came out in the middle of gen 8 and most of its lifetime before being replaced will be while only other gen 8 systems are on the market.

Switch 2 and PS5 and XS will be gen 9.

I said never. Cuz I think PS4 is gonna end up between 120-125 million, while Switch will end up in the 110-120 million range.

Technically there isn't any console ever to not die hard in it's last years. And absolute numbers are what matters anyway.

Did it take like 4 years for us to see another system after the dreamcast?

Your second paragraph is priceless because even if the part about coming in the middle was true or the last part had any relevance to generations, it would mean the dreamcast was 5th gen. Both switch and dreamcast released 4 years after the start of previous gen. A little earlier than usual but not in the middle of anything. Since time of release is all that matters in this subject, that makes the dreamcast a 6th gen, switch a 9th gen, and ps5/xsx/switch 2 10th gen. How long existing consoles over/understay their welcome is completely irrelevant.
