What is this nonsense about "Nintendo knows this and that and have learned X and Y" always being thrown into every argument. They clearly haven't learned and have shown time and time again, the three past years being the closest for evidence, that they do not learn and aren't able to keep up at all times, they have reverted back to becoming followers instead of leaders in the market and shown very poor judgement in the development process, architecture, philosphy and launch of the Wii U and have very much set themselves up for their current predicament, it was long in the coming and all but obvious from the first time they showed the Wii U.
Their stress and rush, paired with the inability to see the importance of things such online features and gaming, ease of use in connectivity with other players, uniform formats, full support for 3rd party peripherals and something as given as advertising shows a company that is living in the past.
Going from the destructive force that was the peak of the DS/Wii combination and into this; Wii U barely moving and the 3DS combating against the approaching death of the dedicated handheld market (another thing that is/was painstakingly obvious to many without Nintendo goggles on) shows that they are far from infallible, they are not contemporary enough, out of touch with the technology applied in almost all gadgets, oblivious to cost efficency and getting hardware for their buck (SSD drive with no room and a super expensive tablet controller that is trumphed by all other tablets on the market?) and, most of all; damn stubborn and set in their ways.
Nintendo are too Japanese to succeed in the West in their current state, its as simple as that. They have made grave mistakes and shown poor judgement of the console market, they have underestimated their competition, riding too long on the ripples of the Wii's viral marketing and grown too fond of their own ways and exellence to see the need for renewal, keeping pace with the market as a whole and humility in any form.
OP: You need to wake up and smell the roses, which is the current state of the market and Nintendo at this stage. They are not in sync at all and the Wii U was a mistake from the first stroke of the designers pen and there is nothing that any amount of games, peripherals or pricing strategies can do about the core problem; the basic lack of appeal and the miscalculated and highly erroneous design and aim straight between two markets where neither is being reeled in and most likely never will be.
All your Nintendo related posts smack of a naive and surreal lack of insight in how things work as a whole, you sound like the dreaded Sony fan anno 2007, the nemesis of all Nintendo fans across the globe.
