The wii capitalized on a motion control fad that grabbed the market share of casual gamers and made millions of new gamers (think guitar hero but on an infinitely more massive scale) and the lion share of those either got their motion control fill and have moved on to other fads or have converted to tablets / smart phones.
Nintendo definitely is still a valid brand and this has happened before circa 1990 when the SNES was still a year away, the Genny was out in the US touting "genesis does what nintendon't" and Nintendo was propping themselves up on the Gameboy (eerily similar to now?).
The difference (and why I'm concerned) is that the major competition this go around are deeply seated (sony and MS both have 2 successful systems under their belts) neither nec nor sega had much of a success (focusing solely on the home consoles) until their 16 bit offering, and Nintendo's biggest problem in 1990 was market saturation. 1 in 3 (29 million at the time) homes in the united states had a Nintendo, and they'd been riding a winning streak. (just to add perspective the ps4 world wide is at 18.5 million and the wii u is approx. half that). Nintendo has posted a lost since fiscal year 2011, and have just since posted a positive 3rd quarter earnings (fiscal year 2014) thanks to ssbm and Mario kart 8 and a half way decent holiday season.
I can understand the closing of Nintendo power simply because the death of print media seems eminent but shutting down a loyalty program... Everything has loyalty programs. Hotels, grocery stores, hardware stores, game stores, department stores, electronic stores, heck almost everything has some sort of loyalty program attached. Nintendo seemed to pioneer that in the game world and I think was doing a great job. Sony and MS has some freebies for having their paid services but Nintendo rewarded people for just purchasing Nintendo products.
And yes, Nintendo says they're going to launch a new loyalty program but what possible gain could come from completely shutting down the current one? A hiatus perhaps, or at least make the coins transferrable but instead they're opting for a complete retooling, why put off what most likely is the most solid of a company's customer base? I could even understand making the coins expire (which is a trend a lot of loyalty programs have adopted or abolished as their needs saw fit) but in the history of retail I cant find an instance of a company completely nixing a loyalty program to make way for a new one.
