In VGCLand you're just happy when they bite on any part of your thread.

I'm going to go out on a limb and predict that the Switch will beat the PS4.

IMO, I would rank it something like this:

SS: 136M+                     PS2 and Nintendo DS

S: 101M-135M                Wii, PS1, PS4, Gameboy

A: 71-100M                    3DS, PSP, GBA, 360, PS3,

B: 46-70M                      SNES, Xbox One, NES

C: 26-45M                      Atari 2600, Sega Gen/Mega, N64

D: 11-25M                      Wii U, PSV, Gamecube, Xbox  

E: 0-10M                        Everything else. Includes Turbografx, Intellivision, Gamegear, Saturn, Dreamcast, etc.

Personally I think E tier should be included as these consoles put a significant financial strain in most cases for the manufacturer and, in some cases, even caused their demise as a hardware manufacturer. And I think that jumping from 30 to 50 million between tiers is just too significant of a bump. Spreading this out by increments of 5 makes more sense. E is 10, D is 15, C is 20, B is 25, A is 30, S is 35, and SS is beyond. This allows for getting up to the next tier to be a more significant accomplishment every time. Going from B to A shouldn't be the same difficulty as going from A to S as it is in your chart IMO. 

200 million is definitely not possible, in fact 170 million is also not possible, the switch has another 3 years before the next Nintendo console, and there's less and less people without one. I don't see Nintendo selling another 80 million in 3 years unless there would be a big price drop.

If they manage to keep current sales numbers they could hit 150 million and that's my prediction. I guess numbers will drop over time when the ps5 and xbox became in stock constantly as those will gather more interest. But on the other side switch will have some boosts over christmas.

It can be difficult to understand why the Switch is selling well.  I hope this video helps.

This is now clearly going to be Switch by a large margin, only DS and PS2 at this point have any chance of staying above LT Switch sales and that now hinges on how the next two years go. 

I still remember there were some users in this thread believing in artificial scarcity bullsh*t that was never proven right even in the past.

SS tier is for those fascist consoles that can prove their German ancestry back to 1800.

Wtf lol ^

my last comment in this site was over a year ago man...

I think i'm quitting gaming-sales discussions i just moved on in my life, that said i went back to VGChartz to see something and i remembered about this thread so now that Switch has officially surpassed PS4 lifetime, the verdect is decided, Switch won.

Thanks to everyone who commented the thread, wish everyone good discussions.
