Indutry, thirdpartys and sony/ms fans are decided to get rid of nintendo this gen

[Tachikoma]

Nintendo's primary franchises are burning out with the average customer, favor for the franchises in the companys native japan has been progressively dropping due in part to the penitration of mobile devices and tablets, and franchises such as angry birds and mobile apps, specifically in Japan, the relatively new chat service NAVER LINE has grown exponentially over the past year from - from wiki so take with a grain of salt:

As of November, 2012, LINE has more than 74 million users worldwide and is used in over 230 countries.[3]
As of Jan 18, 2013, LINE reached 100 million users worldwide, and reportedly gaining about 400 thousands users daily.[4]

It should be noted that registering an account requires confirming an active cellular number in the country you're registering from, so the number of 'dupe' accounts will be very low.

Along with the chat program comes games such as LINE POP, LINE Hidden Catch, LINE Bubble and some others - these games are spreading like wildfire and every where you turn in japan you see people on their phones playing them, the conventional consoles such as PSP and 3DS are still very popular but the primary franchises for nintendo are in decline, the monumental shift late in this generation if seeing once household names being abandoned and left only to the dedicated fanbases of such games.

For example, advertisements are fairly frequent on japanese TV, and WiiU commercials across all channels run 20+ times an hour, often advertising the online functions or mario games, but the interest is just not there, it's as if the only people that are going out and buying these are the loyal fans, the insane growth seen by the wii from customers who wouldnt normally purchase a games console, is just not there for the WiiU, as a result we're now seeing the situation Nintendo are currently facing, and they're just handling it terribly, releasing new (yet old, and lesser-features) hardware into a market already extremely confused about the product - most 5-16 year old kids (a large hunk of Nintendo's customer base), more often than not do not believe or know that the WiiU is actually a different console, more than its a 'different version' of the Wii which they're already bored of.
