Switch ending at 25+ million would (will even) mean that it sold 53+ million in only 2 years, that's absolutely huge

You are forgetting handheld sales.  When you factor those in, Nintendo is #1 more times than not.  However, even taking handhelds into account Wii U + 3DS really was a low point for them, so the "comeback" statement still applies.

Typo, unless...

Just looked into something:
*Rounding

NES 62 million
SNES 49 million (21% decline)
N64 33 million (33% decline)
GameCube 22 million (33% decline)
Wii 102 million (467% increase)
Wii U 14 million (86% decline)
Switch 100+ million (714% increase and growing)

GBA 82 million

DS 155 million (189% increase)

3DS 76 million (51% decline)

Switch 100+ million (142%+ increase)

*Not counting GB/GBC because they are tracked together even though GBC had Superior specs and hundreds of exclusive games that took advantage of the power.

What I noticed about this is Nintendo has two naming conventions. One is using part of the name of previous console, such as the "N" for "Nintendo" located within NES, SNES, or Wii in Wii U. These systems, compared to their predecessor (so all but NES) had on average a 47% decline gen over gen. The other naming convention, where the names are unique, has the systems GameCube, Wii, and Switch. These systems averaged a 383% increase gen over gen, and that will keep increasing as Switch sells more.

On the handheld side, the DS and Switch have a average 166% increase whereas the 3ds, which inherits the name ds, saw a decrease of 51%.

In conclusion, names matter. More than anything else, honestly,  because consumers aren't very aware. If Nintendo has learned their lesson, the next device won't have the word Switch in it at all and will be unique sounding and unique visually.

Probably because of the heavy drinking. Seriously though, I sometimes get confused when I see people ask "Trunks" a question about numbers and for a moment I think they're asking me and I'm like "I don't have a clue!"

Nintendo Next. Yeah, you heard here first. 

I don't think there is much to learn from the SNES that would really apply to todays market. The NES didn't really have much competition, the SNES did.

The GBA sold way more than both the GB and GBC separately in a very short time and the reasons for the 3DS selling less than the DS had nothing to do with it's name.

When the Wii U released the Wii brand had already significantly lost in mindshare and it's marketing together with the name lead to many people not realizing it's a new console. Was it called Wii 2 or Wii HD it would have definitely sold more, but a completely new name would not have helped that much because of all the other issues.

The mindshare of the Switch brand is massive and I don't see it tanking because I don't see it experiencing significant droughts the way the Wii had in 2011 and the Wii U had throughout it's life. It's successor's marketing will not be as terrible since they are learning from mistakes.

While yes, names matter, the declines mostly happened for different reasons. All Nintendo needs to do is not run into the same mistakes they ran into with the Wii U and 3DS and do what they did with the Switch and launch it with strong marketing support, a big system seller right at launch and a big lineup in the first year. Unless the hybrid concept for whatever reason turns out to be a fad and people loose interest. But I think if that was to happen there would already be signs of it going to happen, like big yoy drops.

Makes sense. Would be ludicrous if it actually sold that much there.

Some people (well, one guy who was getting thumbsed up) in the main page story for this week’s sales charts seem to think that VGChartz is artificially boosting Xbox numbers. That seems incredibly silly to me.

I haven’t been here long but I’m sure this has happened before? “Console I don’t like is selling better than I think it should so therefore VGChartz has an agenda”. People need to not get too emotionally invested in these companies
