Except the "outlier" here comprises 16.5% of your data. That's far too significant to just dismiss out of hand. This isn't just a few weeks here or there, it's an entire generation.

Like Rol said, you're basically just ignoring anything that isn't convenient to your claim. If you're going to compare this to an experiment, then what your doing is something known as 'fishing' for data. Which means that you're looking for data to match your claim, rather than the other way around.

So basically you understand the market better than anyone else, right?  Just because someone has an explanation of why something happened and it looks like it makes sense, doesn't really mean it's actually true.  If it really were as easy as you make it seem, no one would have trouble selling product.  Saying it wont happen again just tells everyone that you're arrogant.  It lets everyone know that you think your opinion is above everyone elses (because predictions are not fact).  

Also, you have no idea if the Wii was an "anamoly" or not.  There isn't a big enough sample size for anyone to say if the trend seen warrants that the Wii was the odd one out.  People just say it because there's no other data to look at.  Sure there's reason to think that it may trend downward further, but the fact that the Wii is there shows that there's reason to doubt too. 

 1. You can do what I did and take the WII as an outlier and show that the trend of Nintendo console sales has constantly been a slope.

2. You can do what DarwianEvolution did and state that seeing thus trend one can also state that Nintendo console sales are dependent on the competition 

3. You can do what Rol did and state that Nintendo choosing an unconventional path with the NX will lead to a huge boost for Nintendo console sales.

The OP's content was my take on the data and the User's content are there take on the data. At the end of the day they're all correct until proven incorrect.

I asked a question at the end of the OP for a reason, I wanted to hear everyone else's take on the data.

Edit: It seems like the first line I wrote got combined with your post, just for clarity sake.

I think it's fairly safe to say the Wii is an outlier. It was fuelled by an audience that simply doesn't really care for home consoles in the long run IMO. 

Good luck to anyone trying to get casuals away from their smartphones/tablets. Very unlikely to happen in the future. 

Nintendo was always out of their element making casual games anyway. While they can do it, it's like asking a master chef to make pizza for a bunch of 9-year-olds. I'm sure he can do it, but it's beneath his abilities and quite honestly the kids would be just as happy with a pizza from Pizza Hut or something. 

Nintendo are master game makers (yes their games are easy to pick and play but difficult to master); making games for people who are just as easily entertained by crap like Flappy Bird was always going to run into problems over the long haul. It was a marriage that was never going to last. 

possible I guess, but it's not easy to sell less than WiiU. Except if they continue with their current strategy, then I see sales being lower than any other Nintendo console.
2D/3D Mario, Smash, Kart and Zelda just isn't enough. They need something else.

If the Wii U was priced, and built spec wise, exactly the same as the XB One, and MS had made the SAME mistakes they made this gen (Kinect, no used games, $499), sure we would've likely seen a different share right now.

We might've even seen a 3rd party split back the other way, in Nintendo's favor.

We might even see this shift if the NX launches asap. We shall see.

Nintendo should do this, Nintendo should do that, Nintendo should just quit consoles bla bla bla.

It doesn't matter. Srsly. No matter what they do, people will hate. There is no target audience, because everyone has such weird ideas about what Nintendo is and where it should go.

dbl post

Animal Crossing, Pokemon, Monster Hunter, Paper Mario, Yoshi Series, Professor Layton. All of these are big sellers, and inb4, they could easily be adapted to home consoles. 

Fortunately Sony and MS will be doing that honor. MS seems to have made the smartest option to not bundle a 200$ + 3D Device with their console, while we dk whether Morpheus will go anywhere yet. 

Nintendo would probably be in 2nd place right now had they done that with enough momentum to probably hold MS off for the rest of the gen.
