The rise in popularity of mobile games for tablets and smartphones has negatively impacted the sales potential for dedicated gaming devices like the PlayStation Vita, Sony has said.

Those are great games, but none of them truly leverage the Wii U's features in a way that proves the system's value. Let me explain with an example - Super Mario Galaxy, while a great game, was not a definitive game for the Wii. They could have released the game on the Gamecube, and the only differences would have been weaker graphical quality, and maybe the dropping of the "star bits" (or they'd find a different implementation). In terms of the experience, it would have been pretty much the same. On the other hand, Wii Sports was a game that couldn't have been done on another system, it was a definitive game, a game that demonstrated clearly why the system is worth owning.

Wii U doesn't have that game. The closest games are the ones I mentioned in a previous post - Nintendo Land, Wii Fit U, Rayman Legends, and ZombiU. Those games give a hint to what such a definitive game would look like, but the definitive game has not yet come. Gamecube never got such a game. Wii U will do OK, thanks to strong games like Mario Kart 8, Mario 3D World, Smash Bros, Wii Fit U, etc... but to get much bigger sales numbers than Gamecube, it'll need something definitive.

And the same applies to Vita. There's no definitive game yet - there's games where the PS Vita version is the best version, sure... but none that establish the Vita as a must-have. That's what's keeping the system from taking off the way that the 3DS has. The Vita does have some features that set it apart from other available gaming systems... but nothing really leverages those features while simultaneously making a top-notch game. Until it gets such a game, it will be limited to adequate sales. Same with Wii U. Possibly same with Xbox One (its post-launch situation is not yet clear).

As for your continued insistence that Nintendo is for Kiddies (and your denial is pointless, you quite clearly said it, even if not in those words) is just sad. Nintendo has always been family-friendly... but there's a difference between that and "for younger gamers".

sales reportedly spiked substantially following the PS4 launch.

I could keep going, but my point has been made.

Hmmm... College guys beaten by little girls, boy band playing MK, and a Glee "star" playing Art game... Yup, commercials geared towards mature audiences. 

But anyway, I'm fed up with this - the whole point of the thread was to talk about Sony's explanation for PSV selling poorly. It's not a thread about Nintendo's target market, despite your apparently desperate attempt to deflect attention. You will notice that most of my posts have touched on Nintendo, but usually to draw parallels to demonstrate my point about the Vita. I recommend that you return to the topic at this point.

... also known as adult gamers playing 3DS in commercials. And I particularly like how you completely ignored the other four videos.
