It did not suceed becasue they barely had any games for it for the 1st 12 months - then they had a few then they didnt for another 9 months, then again no games again etc...
Additinally the price was too high and NINTENDO did not leverage the advantages of the gamepad THey did not execute
THey know this but they are trying to say they failed becasue they were too bleeding edge- which is ironic
Nintendo just did not follow thru on their own vision for hte wiii u, they did a horrible job executing re the Wi u and they did absolutley nothing diffferent to maintain any sales momentum- they just sayt there and started cutting back their dev and marketing budget after the 2nd fiscal year of the Wii U s life- that should tell anyone all they need to know- Why would 3rd parties develop for a system that it Nintendo istelf did not beleive in??? They did not. Why would the consumer buy a system thaat Nintenod did not beleive in??? they did not.
