This guy is 98% right. The only thing I disagree on is that developers, analyst and game journalist are fanboys too. Sony having Insurance, Music division, TVs, Phones, Movie Division and Laptops can make fans of Sony. The media is in bed with these mega corporations (Microsoft too) and want Nintendo out. You know it's bad when game developers and analyst talk with hate openly about Nintendo. I remember the doom articles and videos before the Wii U launched. What was Nintendo thinking naming it Wii U, It will be irrelevant when the new playstation and Xbox comes out, Nintendo needs new IP's...... The fact is, the Wii U eDRAM is better then the PS4 GDDR5.

Good post. 

I'd just add to that:

d) demographics ... Sony/MS market almost entirely to the same demographics that the majority of the third parties do, at least with their big gun franchises that being hardcore male gamers aged 12-35. So that makes third parties favor those platforms more for games like Grand Theft Auto and Metal Gear Solid. You notice there is no bias against Nintendo from most family/fitness based third party titles ... Nintendo gets all the LEGO games, Disney Infinity, Skylanders, Just Dance, fitness games, Scribblenauts, Sonic, Rayman, etc. Why? Because Nintendo has Mario, DK, Wii Fit, Wii Sports, Pokemon, Kirby, etc. and third parties figure the demographics are there for cartoony/family/casual based fare. And Nintendo markets specifically to the family/kid audience. 

Beyond that I don't think Iwata-era Nintendo really bothers to engage Western 3rd parties much or at all on a regular basis. They work with Japanese devs on things like Monster Hunter and Yokai Watch and Dragon Quest bundles ... but in the West? Almost nada. I think they are simply out of touch with the Western dev community that is aggressively courted by Sony/MS all the time.

The fact is, that this is still completely made up, don't talk about stuff that you obviously don't understand.
