The article completely lacks industry context. To people largely ignorant of the market it seems like the whole reason for Wii U underperforming is lack of software, which it doesn't actually lack anymore, and people playing on their tablets, as if the console market in general is suffering a catastrophic collapse. Even I'm not that pessimistic, and seeing how PS4 has continued to sell very well through the northern summer and has been spanking Wii U everywhere but Japan, which might be the onebplace there is a catastrophic collapse in home consoles, puts a totally different context to Wii U's predicament. Fact is it is failing to compete with its direct competition, and this rather than broader console existential issues is the reason it is where it's right now, and has very little chance of any meaningful turnaround.
It is really Nintendo's systemic and long term (basically since NES) failure to understand the gaming market which sees Wii U where it's at. Or they ilunderstand the gaming market, but choose to only appeal to a niche minority. Make no mistake, Wii did not appeal to the gaming market, it appealed to the non-gaming market and that is why it only had 4 years of huge sales, followed by a collapse both for the Wii and it's next gen offering. And they still don't get it.
